When I masturbate...which I alot :wink:...I love ending with nipple play. When I am ready to bring myself to orgasm, I lightly "tickle" or stroke my nipple with my right hand. With my left hand I stimulate my frenulum in a circular motion at the same time. I find the orgasm to be one of the most explosive cum shooting orgasm ever. I also love it when my girlfriend does the same while we are having sex...but usually have to make her stop since my nipples seem to be wired to my cock. Have any other guys tried this? Lets hear your story!
