It did it! Dammit!

Well, kind of yes and kind of no on the dammit part. I am as many still awaiting the super-0 but as it has just been since February I will be patient. What I am writng about is the use of the progasm during regular masturbation session not a non-penis session. The other day, and this has been increasing in intensity all the time, I had the most unusual thing happen. Well, unusual to me anyway. I have found that masturbating with the progasm starts out with some p-waves that increase in intensity the longer I masturbate and hold on the edge of traditional orgasm. They are now to the point of intensity and pleasure that about all I can do is stroke and damn near drool all over myself because I am not capable of anything else! This last time I stopped masturbating and tried to hold off on orgasm then the (probably not so unusual to you all) most unusual thing happened. My body took over and basically seemed like it was "fucking" me with the progasm and pumped and thrusted until I came anyway (very very intenselt)! This was about a minute or so of pure bliss. Anyway, is this normal? Thanks!
