Newbie help, getting there

If you read the quick and dirty path,plus b mayfields posts up on the stickies,there is detailed help and instruction. It’s may not be just about involuntaries. When it’s good and the auto fuck is going,if you starting thinking on orgasm,it’ll fall off the table,you want to just enjoy what’s happening in the moment,try to forget orgasm altogether.
And start a kegel and meditative breathing regime. I think the pieces are all there already,you just have to quiet the mind.
I squeeze and hold both pc and sphincter,usually 20 - 30 secs,eventually one or both begins to fail and still try to grip,this is involuntaries.

@Infinity46 Deciding to make a push for the super O will turn the outcome of your session into 'not gotten a super O'.
Your thinking during a session will be 'what do I need to do to get there' and it will become a quest for the holy grail.
Definitions of what it even is tend to differ. For me personally, I don't even like the terminology but I have had Orgasms that I could describe as being 'super' but I choose not to describe them. These are very rare though and a blessing. Thinking there is anything I can do to get them is not constructive.

More normal orgasms are less rare but not guaranteed at all. I think the best way to get them is to accept the fact that you won't and still enjoy yourself. Savour sensations like how you describe getting auto fucked.
But you "couldn't hold it so never came", this mode of thinking means that you failed. Pretty much 100% of the time. Is it even possible to experience this throughout? Is it needed to orgasm even? What if you can orgasm from just pressure alone if you are aware and sensitised enough?

I think the best way to induce involentaries is to learn how to feel what all the muscles there are doing and where the pressure is. This is more difficult than it sounds. Movement can happen on its own and without the active involvement of yourself, that way there is also no way to do it wrong.

@Infinity46 , both @Tommygunn & @Mitaru gave you good advice.

... recently have decided to make the push for the super o.

My intuition is telling me you may be trying too hard to 'make' something happen. If this is the case you need to remind yourself that you can not force your body to produce results your ego wants to happen. Prostate orgasms will happen when your body determines the conditions/circumstances are right, trying to force the process is counterproductive and will usually result in shutting down the session.

Ive been having great success in my sessions. Theyre all pleasurable and fun, but I cant cum.

Perhaps you are still fixated on the sensations generated from a traditional ejaculatory orgasm. Prostate orgasms are qualitatively different from the ejaculatory orgasm but if you are looking for the same or similar sensations/feelings you may be missing the prostate orgasm. This is a form of perceptual blindness to which we're all susceptible.

It seems to go away after a little bit so I dont know what to do.

There is a cyclical nature to the generation of P-waves and prostate orgasms, this is quite typical. You may need to wait several minutes between sets of waves, all I can advise is to be patient but listen to your body, it will generally signal in some subtle manner when a session should conclude.

Also, does anybody have some good methods on how to induce the involentary contractions?

Early on in my Aneros Journey I found that trying to hold a continuous low level (20%-30% tension) contraction could initiate some involuntary contractions, you might try doing that.

Thats the thing. Im not really "trying." Just getting horny and playing with my ass going with the sensations. Ill get to the point where contracting will feel tingly in my prostatw and it will start to swell and feel reallly good but if I keep contracting it just gets numbish and unswells. Also, have you found more success when abstaining from a session or not masturbating for a long time? Farthest Ive gone is a day without. Maybe if I waited a week I'd cum easily?

Don’t allow yourself to imprison your mind with things like..I must have a certain set of circumstances to have prostate orgasm.
i had morning sex at 6am with my wife a couple of weeks ago,she went to work,and I was off,I had a session at around 2 pm and had a super-o,if you can open the door,you may learn that what the prostate can do is virtually limitless.

but if I keep contracting it just gets numbish and unswells.

The reason why I advise the 'do nothing' approach is because I also have this what you describe. I can use contractions to get things going or just for the hell of it but I find it hard to keep anything going with it (not a strict rule). The way I see it is that if you clench you restrict movement because you 'force' a certain pressure or whatever. Leaving little room for your body to pick things up. Smaller motions or relaxation often work better for me.

It makes sense to think that things need to get bigger. That you need more pressure and more movement but consider this analogy: I don't know if this applies to you but it does not matter, but take porn for example. You can go onto this path where you need more extreme things to get off. This will often have a limitation because after a certain point you will have hit a ceiling. Going the other way around and sensitising yourself to softer stuff, or masturbation with easy relaxed, slow motions or teasing won't have this ceiling but will paradoxically heighten your sensations and can get you horny from almost nothing.

I think Aneros play works in a similar way. It is with intense focus and awareness on subtle sensations where you can go to a place where you become more sensitive and respond better instead of making motions bigger. This is a learning process though and will evolve over time. Patience and an open, non-judgemental mind are good things to have here.

Abstaining from masturbation falls within the sensitising yourself realm and can help if you like to try that and is often adviced on this forum.

@Mitaru I think you hit the nail on the head! I think too much porn isn’t good for anything Aneros.. That may be why a lot of guys are struggling to achieve prostate orgasms..

Ill get to the point where contracting will feel tingly in my prostatw and it will start to swell and feel reallly good but if I keep contracting it just gets numbish and unswells.

OK, so now you've found if you "...keep contracting..." your session goes downhill, that's an example of trying too hard to make something happen. When you first detect the contractions losing effectiveness is the time to back off and listen to you body, see if your body signals some other action to take, perhaps it will signal a change of position, perhaps a change of breathing pattern or some other little action. These are very subtle signals but you have to be looking for them and not ignore them when you do detect them.

Also, have you found more success when abstaining from a session or not masturbating for a long time? Maybe if I waited a week I'd cum easily?

Yes, having a high arousal level (please see Are you "aroused"?) is important to get to prostate orgasms and practicing some form of temporal abstinence/semen retention can help elevate your overall arousal level (please see Aneros, Arousal & Abstinence). If you really want to see where you natural homeostatic arousal level resdides then I'd suggest you take 21 day challenge.

@Mitaru I think you hit the nail on the head! I think too much porn isn’t good for anything Aneros.. That may be why a lot of guys are struggling to achieve prostate orgasms..

That's actually not what I meant. I just used it as a way of explaining different paths of arousal and should have chosen my words more carefully. I'm perfectly fine with porn watching and don't think it gets into the way of Anerosing.
For me personally, I like to watch porn during sessions. If it feels distracting or annoying I turn it off. Most sessions are without porn watching though. I have my eyes closed most of the time anyway.

If you feel like you are watching too much of it though, that could impact your arousal levels and might be something worth looking into. This subject is difficult and personal enough to not make any broad statements about and I'm certainly no expert on it so don't want to offer any advice on the matter.

@Mitaru i very rarely watch porn,just doesn’t do it for me,and find it distracting with anerosing..

When I was first trying to have prostate orgasms, I tried the involuntary-inducing method of contracting and bearing down simultaneously. It worked to create involuntaries, which felt good, but it also preventing me from going any further, as it sort of made me numb down there to the point of the session losing its steam completely. I ended up trying other methods, and what worked for me was very minimal contractions (as @rumel says, 20-30%), which allowed me to focus on the gentlest of sensations. With very gentle contractions I was able to learn how to move my aneros in many different directions: up, down, forward, backward, left, right. When exploring these directions (I am switching to the present now, as this is my current technique), I find pleasureful areas, or certain movements that give me a lot of pleasure, and those become "seeds" for orgasms. This is all possible for me only under light contractions and a very clear mind, which allows me to focus on the slightest of sensations and thus amplify them. Only several orgasms in, when I am much more sensitive, do I go on to larger contractions, or forced involuntaries, but even then I usually avoid them.

Everyone is different in terms of masturbation and its relation to prostate pleasure, from all that I've read on this forum. For me not ejaculating for several days (multiplied by masturbatory edging, hours-long sessions of erotic play/sex with a partner without ejaculation, and solo aneros sessions) turns my prostate into a glowing orb of pleasure, and that's when I have my most fantastic sessions. And when I had my first prostate orgasms, it was when I was in a prolonged state of ejaculatory abstinence. But abstaining from ejaculation isn't necessary for my capacities to have a multi-orgasmic blast of a session!
