A question about anal intercourse...

The obvious answer is that you believe wrong.

Wow @Bunk, what a great provocative question, not daft at all or a wrong one! One answer is that yes our anus and rectum does provide some mucous and sweat which provides some lubrication. Another answer is that men's penises provide precum which is a superb natural lubricant. So there's that connection.

Wikipedia says "The anus has a relatively high concentration of nerve endings and can be an erogenous zone, which can make anal intercourse pleasurable for both the insertive partner and the receptive partner...In addition to nerve endings, pleasure from anal intercourse occurs due to the shared wall between the anus and the prostate for males and vagina/G-Spot for females. This allows for indirect stimulation of the G-Spot or clitoral legs in women, and prostate in men.[6][7][8][9] For a male insertive partner, the tightness of the anus can be a source of pleasure via the tactile pressure on the penis.[8][10] Pleasure from the anus can also be achieved through anal masturbation, fingering,[3] fisting, facesitting, anilingus, and other penetrative and non-penetrative acts. Anal stretching can stimulate the nerves around the anus and can be considered pleasurable." *

I find that the more pleasure I'm receiving and giving to my sex partner, the more natural lubrication we put out. It helps to start off with a store bought lube though for insertion as I'm sure you've found out with aneros insertion 🙂

I think the aneros devices will necessarily need more lubrication because they are a hands-free massaging device whereas anal sex is a shared experience. Too much lube can be a disadvantage with anal sex IMO as it decreases sensitivity for me. Depends on what you like I suppose.

Because the anus isn't intended for sexual play. Anal and prostate orgasms require a lot of practice and time to get proper sensations for some, hence (partly) this forum.

Am I the only man here who has had anal intercourse with another man? Why don't you others, gay or bi or curious or transgender men, have an opinion or something to contribute to this topic? Aneros practise and anal sex are different from each other in important ways. What are they? Do they both require a lot of practice and time to master? Is the vagina the only body part or gender part intended for sexual experience? What about the mouth? Who doesn't li like oral sex? Why are the str8 men the only ones commenting on this important topic? Inquiring minds... 🙂

I do not, in any way or form, believe anal intercourse to be intended by nature. The bacterial flora in the rectum and no natural lubrication are two indicators of this. Also the rectum is built to push out, not have anything go in - this is countered by aneros design.
The location of our prostate is not connected to anal intercourse, it is however a good location for feeling pressure when a BM is needed. It is also a good location for feeling when the bladder is full, which is also connected to your BM. Aside from that, it is a natural placement for involvement in regular hetro intercourse. It also seems to be a natural placement when the body develops into the defined male/female sex. I personally believe that the prostate is the same "part" that develops into the G-spot in females.

What we are doing with focus is actually hacking and suspending the regular male orgasm into an inward full body orgasm. Releasing the same reactions in the body and the brain as through a regular orgasm or with drugs like E.

Either that, or magic 🙂

It most certainly happens in nature, most notably with Rams, whether or not nature "Intended" it. Iwonder what they use for lube!


http://en.wikipedia.org/wiki/Homosexual_behavior_in_animals

we *know* that the vagina is intended for intercourse because that is how the species reproduces.

about the rectum being "designed" for anal intercourse, that is not black or white. evolution does not work in black and white. is the rectum as optimized for intercourse as the vagina? no. is it possible that *some* of its structures have in *some ways* been influenced to function for anal sex? we can't really say either way. what we do know is that it is proximate to nerves that respond well to stimulation from inside it, and that when that happens, the rectum responds by contracting around that stimulus.

is it possible that there was somehow some evolutionary pressure that made men who were sexually responsive to anal sex better at reproducing? seems kind of like a long shot, but not impossible.

is it possible that the responsiveness we feel in our rectum, anus and butt are carry overs from female anatomy? likely.

since we can't rewind the tape, it's hard to say. perhaps some evolutionary biologists/physiologists would be able to shed light.

in my view it is not fruitful for people who are advocates or enthusiasts of receptive anal sex to claim the rectum is designed for it while those are less accepting of that to say its not. in other words, there is no reason to turn this into a cultural/political discussion.

darwin

It's okay to have opinions, beliefs, ideas, prejudices or anything else here. God knows we get enough of that, especially if it's a hot button pushing question.

I'm trying to be polite here but (especially @alex_xxx) we all know what some responders with no personal experience in anal intercourse are going to say because they've expressed the same things many times in the past.

Anyone with actual personal experience in anal intercourse care to address @Bunk 's original topic question? Or someone who's straight or curious enough to wonder the same thing as @Bunk? It's a topic area deep in a wealth of pleasure so to speak. 🙂

@didymus, so you are NOT in favor of oral sex because it doesn't reproduce the species or what?

@Darwin, not everything that humans do is aimed at optimizing the survival of the species as your namesake maintains. That's a debatable modern construct IMO.

Just to clarify the original question. Our anuses do not lubricate themselves for sexual penetration exactly the way vaginas do. Nor do they function for reproduction. No one is arguing that they do. Actually a case can be made that our anuses function as a contraceptive outlet for men and women who don't want to have children. Neither are our mouths or any other concave orifice designed for giving birth but they are superb sexual outlets.

euphemstic, i did not say, even one bit, that everything humans do is aimed at optimizing the survival of our species, nor did darwin ever say that. people who do say that misunderstand evolutionary theory.

we are talking here about the anatomy of the rectum/anus, and if it is "designed" for anal sex. we are not talking about behavior.

the only single way anything in our bodies is designed is by natural selection, and to a lesser extent, by epigenetics. so when we ask about the design of the rectum, we are asking about the forces that might have designed it. the only way it can be designed is if it leads to increased reproductive success of the individuals who have the better design (mutation). Here reproductive success does not necessarily mean that they themselves reproduce, but it does mean that their genes have better success. This can be accomplished by their close relatives benefiting from their improved design.

i am also not saying that all aspects of our bodies are designed. some are just accidents. it might be that the rectum is responsive as an accident of the rest of the design of the pelvic floor.

either it is an accident or it is designed; and if it is designed it is done so by reproductive fitness.

i really don't want to go further into this. either you have a correct familiarity of evolutionary process or you don't. and I am not going to spend time here educating those who don't
darwin

@Darwin, I appreciate your nuanced comment above. I didn't mean to imply that you said everything we do is related to reproduction and I have only a vague understanding of and interest in Charles Darwin's theory. I was actually trying to steer the discussion away from that direction.

I don't want to go into evolutionary theory or religious beliefs either as that is off-topic IMO. The original topic is anal lubrication and anal sexual behavior as I read it. "Having been on the receiving end of anal and prostate orgasms, thanks to aneros, I now believe that anal sex between men is a act that nature intended. All the ingredients are there." It's the behavior aspect that interests me too.

what we do know is that it is proximate to nerves that respond well to stimulation from inside it, and that when that happens, the rectum responds by contracting around that stimulus.

is it possible that there was somehow some evolutionary pressure that made men who were sexually responsive to anal sex better at reproducing? seems kind of like a long shot, but not impossible.

is it possible that the responsiveness we feel in our rectum, anus and butt are carry overs from female anatomy?

darwin

Well, when the nerves sense something in the rectum, of course they respond by contracting. If not you might crap yourself. Or even worse, you wouldn't sense that you needed to take a crap.
As for anal intercourse, you are prone to get a urinary tract infection from the bacteria. Nowadays, its ok, you can get broad antibiotics to take care of it. But a century ago, such an infection could kill you. There is also other situations that would end your life by messing with other peoples excrements or anus. This is infact why your first response to other peoples farts - is disgust (from an evolutionary standpoint)

It's okay to have opinions, beliefs, ideas, prejudices or anything else here. God knows we get enough of that, especially if it's a hot button pushing question.

I'm trying to be polite here but (especially @alex_xxx) we all know what some responders with no personal experience in anal intercourse are going to say because they've expressed the same things many times in the past.

Would I need to have actual personal experience with gay anal intercourse to answer this thread? I think not. And I have plenty of experience being on the giving end to the ladies. I dont believe the male and female rectal anatomy is all that different. And judging by my experience, they were never intended (by natures side) to take a dick up the ass. If they were, I'm pretty sure they'd accomodate it more easily without any need for lube or relaxation.

Whether nature intended man to engage in anal sex matters not. Man will fuck anything....two straight men in a cage and one will take a cock in his ass, he maybe dead but the other guy will have a smile on his face.

Compartmentalism is problematic. We have this opportunity to enjoy life. Preferably without harming ourselves and hopefully not harming another. In general terms our bodies have evolved in a certain way, one of which it the continuation of the species. The rest is up to us and a dash of common sense. So the vagina is lubricated because many people will have thoughtless sex - the bottom line. But joy and pleasure are open for many alternatives and explorations. Nature provides many helps for the inquisitive - for example olives produce oil to all sorts of purposes even lubrication. It think we do a disservice to each other to make universal judgements. Fear and misunderstanding can put us into dreadful position of being judge mental and 'righteous' and being cruel and doing evil things to people who are different. The body is wondrous and to be enjoyed, if it is enjoyed it will improve its life energy. It will be healthier and we will be happier.

Having been on the receiving end of anal and prostate orgasms, thanks to aneros, I now believe that anal sex between men is a act that nature intended.
Nature does not "intend" things, it just does things.

But to each is own beliefs and religion I guess. From which comes, this subject may probably not be discussed unless we are willing to at least mildly accommodate with this belief.

All the ingredients are there.
Obviously not, and far from it, as you contribute stating yourself next.

Same goes for women whereby they can have sex by rubbing their clitorises together (among other delightful-to-watch methods).
Absolutely not the same (not going into it here, cause both vast subject and off-topic). Plus, porn is not reality, and in the case of portraying of lesbian intercourse, they say themselves it is even the farthest from reality you can get (a bit of overreaction here from the offended maybe).

These have no procreational reasons to happen
Well, direct reason, no. Indirect reason, we could probably sustain a yes.

but they do.
Indeed.

But one question springs to mind; Why then, does the rectum not self-lubricate in the same way as a vigina during arousal..?
How the hell such a question can spring to mind from the previous train of thoughts? To me the logical gaps are so wide I could seemingly pass the entire planet earth through it (without lube).

Could you please clarify ?

On the face of it, a daft question.
Well, you definitely could say that. Yet again, this place is for adventurous experimentation. I wrote and asked myself questions here seemingly far more absurd... And I am glad I did.

But I'm curious as to people's theories
I am sorry, you meant "fantasies", right?

and I know of no better place to ask than here.
Well, I think of many LOL.

... Now, depending on the underlying question you indeed have, there are plenty of different answers, so I'll wait before you clarify.

And if all you care for is fantasies, then I must sign off and leave that to others.

@Canacan said, "I must sign off and leave that to others".Good idea. And thanks for your marking my essay.
I just asked a question about something that I had been pondering. I am interested in what people here think. What I'm not interested in are the ramblings of pseudo-geniuses trying to pump up their own egos by putting down other members based on the way they structure their posts.

Purely accidental in my opinion.

The prostate is where it is because it's close to where it needs to be (the penis).

Remember the prostate isn't actually IN the rectum, it just so happens it can be touched through the rectal wall.

If our anuses weren't where they are then we wouldn't be having this conversation as Aneros wouldn't have been invented.

The very fact that we need lubrication for penetration shows that it's a happy accident.

On a sidenote, I love it when people (usually religious) start talking about what is "natural".

Everything is natural - all the stuff human beings create and do is natural because it comes out of the creativity of our ORGANIC and NATURAL brains.

Ignorant bigots spout off about how "gay sex ain't natural" and then happily jump into an airplane.

Using their logic flying "ain't natural" but they can't seem to see the logical faults in their argument.

Neros,

I am not sure it is so clear-cut as you state. The entire rectum, all sides of it, is erotically responsive, not just the prostate. The anus as well.


I commonly have orgasms that have no direct prostate involvement. They are anal orgasms. Often, when I do so, I fantasize about being fucked and it feels incredible. Incredible to have:

[LIST=1]

I totally understand Bunk's question, because that assembly of sensations is so overpowering, and feels so incredibly good and right, that it is "natural" to ask if our body was designed for it.

As i said in my post above, it is possible that some of this functionality was selected for, or it is possible that the whole assemblage is accidental. We won't ever resolve this question. But I think it is understating the matter to think this is merely because the prostate is proximate to the rectum.


darwin

@darwin yep I don't disagree that the anus is erotically arousing.

But so are the nipples.....

There are tons of erotic zones that people have (including some really weird ones).

Your anus is jampacked with nerve endings because it helps you know when you need to have a bowel movement (amongst other things).

Unlike the penis, just stimulating the anus and the prostate isn't GUARANTEED to cause orgasm alone.

99% of us have to "learn" (aka rewiring) to have orgasms from anal stimulation (and the time that takes varies from person to person)

The same with nipple orgasms for example.

What I'm saying is that you can stimulate the penis nerves and even if you aren't actually aroused, your penis will become erect and you will ejaculate and orgasm.

To have a rectal, prostate, nipple, full body orgasm etc. you typically need to fill that stimulation with aroused energy. It needs to be arousing.

Remember the saying "the brain is the largest sex organ"

Getting fucked in the ass by a cock is obviously an erotic act and that would provide enough erotic charge to turn that anal stimulation into an orgasm.

If all it required was nerve stimulation then you'd have an orgasm everytime you took a shit. (though sometimes that happens to people I've heard).

I agree with you though for the most part - its not a black and white issue.

Neros,

All you said about anal and nipple eroticism could equally describe female eroticism.

You cannot get a vagina to orgasm without arousal. That is what women are constantly needing to drive into the thick heads of men, who I agree, are equipped with a hyper-responsive sex organ. However, I don't think anybody here would argue that female eroticism and orgasm is an accident.

So, that need for arousal to have anal orgasms I don't see as an argument, in itself, against design.

Darwin

i often wonder why we have a prostate, i wonder why we experience extreme pleasure from it. A method of nature keeping us wanting sex? perhaps. I oft feel we are hacking nature in having prostate orgasms, but i also feel that there is hidden knowledge, perhaps in previous civilisations that is being rediscovered in some way.

@inhope,

implicit in this whole question is: what is the natural history of male receptive intercourse?

the only way this could be designed for is if somewhere in our species' ancestral past, however far back, this was a practice that was common enough to positively impact natural selection.

it being practiced in scattered rare societies not on our ancestral line would not argue for design, unless there was a more ancient (i mean in the hundreds of thousands of years) common ancestral practice.

darwin

Well we don't know if the sumerians did it, though there are suggestions of it... anyways, what i really want to know is WHY we orgasm, what is the need for orgasm? it only seems to serve the purpose that it creates a need and keep us reproducing.

I also wish that a super o was a natural state for all men, meaning that we all could have them no matter what.

Imagine if every man could know what a super o was like, I'm sure there would be less fighting/wars/murders, if only by the prospect of the distraction of taking years to potentially achieve one...

I'm sorry if I offended anyone with my crude expression. All I'm trying to say is that it doesn't surprise me that when anal intercourse is mentioned, str8 identified men mostly agree with each other that it's unnatural and go off on a clinical scientific tangent. It's an uncomfortable subject for some men.

I can't prove it but man on man sex has probaby been going on since before our Neanderthal ancesters and even our pre-human ancesters. It's just been undercover for much of that time so not taken into account.

By many counts there are more men here who identify as gay, bisexual, transgender or curious than there are straight men. So why is it that mostly straight men (as far as I know) have responded to this topic yet have not addressed the original question adequately? I'm not telling anyone to keep quiet; I'm just not surprised that my gay, bi, and curious brothers here have largely avoided commenting on this topic. And that's too bad for everyone here.

Anal intercourse between men is one of the most profound sexual, energetic, spiritual transpersonal experiences I've ever had, period. It's a complete deep bonding with another human being. Maybe that's why I get so excited when this subject comes up. @Bunk, you don't absolutely need lubrication for anal sex. I know this from experience.

Euphemistic,

Not to be pedantic, but the Neanderthals are only barely our ancestors, and not in all populations of humans.

Plus, how can you possibly know that male-male sex happened before humans were able to provide recorded history. Are you saying there are fossil remains of early males fucking?

When you make statements about anthropology and human evolution, you'd be best off knowing the facts.

You are pulling the same defensive, and biased, stuff I see gay guys doing all the time. I understand that, being oppressed, defensiveness is somewhat expected. But, if you look in this thread there are many straight guys who are not saying that male anal sex is unnatural. As @neros points out, "unnatural" is a ridiculous and vacuous concept. You are among people who by and large are very accepting of male-male sex. As a population of mostly straight men, you aren't likely to find a group more so.

I, at least, am discussing something simple, as posed by the original post by @Bunk: speculating on the natural history of anal sex, and if our body is designed for it.

Just because you find anal sex spiritual, which my fantasies lead me to think I would too, does not mean our bodies were designed for it.

darwin

@Darwin, I have 3 percent neanderthal DNA by testing. I guess there was some interbreeding going on back then. So they are ancesters to some of us"hybrids". 🙂 I'm not putting myself out as an expert in anthropology either. Just pointing out some things I know and connecting them. All I'm saying is that it seems obvious that anal sex has been going on for a very long time.

I appreciate what you and some of the others are saying and am not accusing you personally of being unresponsive to the question. But I stand by the thrust of what I've already said about the dynamics going on here. I agree we're a very tolerant group on the whole and I value that.

As for being defensive, I guess I'm not the only one guilty of that fault. I get that accusation all the time so am used to it. I do tend to get defensive when my deepest sexual experience is described as unnatural by some men here, as it was. I understand that this word is being used in different ways by different men and is not meant to be offensive. It's just the unthinking use of "unnatural" here that bothers me and that I'm pointing out.

@Darwin, I'm always glad to hear what you say and others here too.

Neros,

All you said about anal and nipple eroticism could equally describe female eroticism.

You cannot get a vagina to orgasm without arousal. That is what women are constantly needing to drive into the thick heads of men, who I agree, are equipped with a hyper-responsive sex organ. However, I don't think anybody here would argue that female eroticism and orgasm is an accident.

So, that need for arousal to have anal orgasms I don't see as an argument, in itself, against design.

Darwin

I daresay you could get a clitoral orgasm without being aroused.....

Given that the clitoris is basically the head of the penis. Just stimulating the clitoris does cause orgasms.

The clitoris is extremely sensitive and is hyper responsive. Little girls, way before the age of knowing about sex, suddenly discover this area feels good without knowing why.

Vaginal orgasms on the other hand are more like our prostate orgasms and DO require arousal yes.

That said, the anus and spincter do play their role in our "normal" orgasms (clitoral or penile) by pulsing for whatever reason.

I happen to believe it is just because of closeness to the gentials that they are "roped in" as a happy accident.

Either way, it feels great and I ain't complaining 🙂

You are pulling the same defensive, and biased, stuff I see gay guys doing all the time. I understand that, being oppressed, defensiveness is somewhat expected. But, if you look in this thread there are many straight guys who are not saying that male anal sex is unnatural. As @neros points out, "unnatural" is a ridiculous and vacuous concept.

darwin

I, for one believe that it is natural. It is only an opinion. It's all I have. I believe it because of how many other animal species practice male to male anal sex. I realize that that the lack of lubrication might be interpreted as the reason it isn't, among other reasons. But, I'd argue that a raccoon does not produce saliva and so it dips it's food into water when eating solid foods. I don't think anyone would argue that it's un-natural for a raccoon to eat. There are many ways that animals adapt. That is natural. Animals practice companionship, they please each other a multitude of ways, simply for pleasure, non-sexual as well as sexual. We are just another, more creative animal.

Not that it matters, but I am a straight male that has never had male to male sex. Prior to Aneros, I had no idea that the anal cavity was a pleasure center.
