Extreme dry orgasm with out a toy

I had at least 3 unexpected strong dry orgasms without the use of any toy!  I had smoked a little and drank a few beers and was pretty buzzed and sleepy...not aroused in the least.

I went to bed and laid on my right side and accidentally "brushed my cock with my hand" and I felt a STRONG sensation in my prostate and I felt an orgasm building quickly ...I had no toy...I was ready to go to sleep and WHAM! I clenched my PC muscles and felt the warm sensation rushing through my body. It was a very strong dry orgasm...my penis never got hard and it lasted maybe a solid minute or so. When it was over I lay there breathing heavy and enjoying the after glow, and here it came again!  I never tried to create these sensations but there was no ignoring what was happening.   My body tensed and I felt a wave of intense pleasure controlling my whole body a second time..and then a third time,..NO TOY or intentions of this happening to me.

I have no idea what made this happen but I hope it does again.  Do not give up on your journey. I have been using Helix Syn and Progasm Ice for the last year with pleasant results but nothing like I felt last night without any toy....
