I've been trying to do this for some time and I guess this would be the best place to get some feedback. Anyway, I'd heard it was possible to reach orgasm without the use of hands or any external object and that it's pretty intense. I think it would involve some combination of mental concentration and kegel-like exercises which I've been doing. So far, I've gone about a week without normal masturbation and have come close on a few occasions. It seems that going the last little bit is the hardest part. Have any of you done this or know someone who has? If so, I'd appreciate any suggestions.
