I've read about how some guys can climax and reach orgasm without any physical stimulation. I tried this a few times to see if it was actually possible and, so far, I've had two successful trials. The first time I had to concentrate as hard as I could and even though I did cum, it wasn't very intense, more like a quick squirt. My second successful trial was more intense than the 1st time but still not as good as what I get when I do the job by hand (PUN). How many of you have or can orgasm just using pure mental effort and is it at least as intense as the orgasms you get from physical stimulation?
