On Friday night the gf and I watched a show called Strange Sex that featured a story about a woman who can think herself into orgasm without genital stimulation. The next morning I was lying in bed and my gf was casually rubbing my nipple. It felt good so I decided to try some of the techniques from the show (tightening abs, breathing, clearing my mind) to see if I could make anything happen. The next thing I knew an amazing pleasure was building throughout my entire body. I soon shook with an extreme orgasm-like burst that felt absolutely incredible. My cock swelled but I didn't cum. My gf said I was warm just like I am after a normal orgasm. I proceeded to do this eight more times which was a first for me and really unbelievable! I figure it was possible in part because I didn't cum and lose that sexual energy. There was some precum leaking out in the later stages. I'm totally amazed that this was really possible. I'm going to try it again to see if I can replicate the results!
