How to clear the mind???

If you can manage 40-60 minutes of concentration you aren't doing too badly! Are you getting dry-O's and just concerned that you aren't having super-O's? or are you not having dry-O's and feel that you are not able to concentrate long enough to get those?

It is difficult to completely free the mind of noise. There will always be thoughts popping up in your head, I think even the Dalai Lama says that he cannot eradicate all thoughts. The important thing is to be able to ignore those that do come along and not let them start a train of thought, and to be able to return to the sensation you are concentrating on.

@smudgefish I don't think I have had Mini-O's, Dry-O's or Super O's, I have had in-voluntaries and I have had some very good feeling and some "Rushes" where it feels like something is building.

@xtimedt69 I notice that you have been doing this a lot longer than I have. There are numerous posts on the forum about 'letting go' and how to build the feelings. You might have read them already.

Perhaps you have got to the point of feeling that it will never happen and there is a mental block and the more desperate you are the more your mind will wander. As you get close your mind will start telling you that it's not going to happen because it never has done in the past. Try to forget what has happened in the past and concentrate on the moment and enjoy it, I think it's a form of mindfulness. Take to just observing what is happening and try to guide it rather than control it, don't fight it, and allow a dry-O to evolve by concentrating on the good feelings. We have all been there. If you are having 'rushes' then you are probably very close to having a dry-O but you are fighting it.

Not sure if that's of any help.

@xtimedt69
I don't see a wandering mind as a symptom of incomplete relaxation. Just the opposite, in fact.

My mind needs something to occupy itself until the waves and involutary contractions get into full-swing and dominate my attention. I asked the group's suggestions for low-level brain stimulation in the thread Anything on the TV besides porn?

What do you suppose brings the headaches? Is it possible that expecting the headache is causing anxiety, like there's a ticking 40-minute timer counting down?

Have you tried breaking a session into shorter segments? I sometimes interrupt a ride after about twenty minutes if it's pleasant but not great. I take a few minutes to go pee, get a snack, etc, then restart the ride. It sometimes converts "good" to "great," like the first segment was foreplay. When the second segment isn't significantly better than the first, I still feel more refreshed by taking the short break.

@PSLabs Ever since I was a kid, if I am in bed or laying down and get restless I will get a dull headache.

I will look at that thread.

In spite of me favouring the do-nothing approach, I do find having a contraction to focus on very helpful to keep me in the moment. Holding a tiny bit of tension in my anus and seeing how lightly I can hold it before it no longer counts. It's like picking something up, lifting it an inch, and then very slowly lowering it down until it touches a surface. And then trying to find that point where it's not quite resting on something, but not quite being lifted either. Feeling what the muscle is doing.

I used to have the same problem with drifting off into daydreams, but I don't think you can fully disengage to that point and still be present sexually. I think there's a part of me that needs to stay awake and focused... it's like an erotic energy. It's like switching off all the lights in the house except one, rather than going for the circuit breaker and shutting off everything at once.

Oh, that's great. Thanks for sharing!

Oh, that's great. Thanks for sharing!It's an adaptation of something I came across while doing my usual dumpster-diving of this forum. A very interesting post from 2004 by ash.

"For me, the key is capitalizing on a sensation that I was quite familiar with from normal masturbation without realizing it. Not to go into explicits, but when I masturbate normally, I tend to anally contract for a short period and then release, then contract, release (much like the contractions during normal orgasm). I've now realized that it is the 'release' contraction which is crucial to starting the Super O (for me). Focusing on this 'release' sensation, and very subtley maintaining it is what triggers the beginning of my Super O's. To give you a better idea, this contraction gives me a sort of 'bottoming-out' feeling in the abdomen. I noticed, even during my early sessions, that within the chaos of my endless contractions, there was a period between 'not-quite-relaxed' and 'not-quite-contracted' which made my body involuntarily twitch."
I still don't know what he meant about the bottoming-out feeling, but the almost-contraction did interesting fluttery things. Very subtle, and something to focus on without trampling all over the involuntary action. This is the post I "took with me" into the best session I've ever had, so I do give it some weight.
