Automatic PC Excercise

[ngt2000]

Whenever I masturbate I just naturally tighten up my pc muscle...I do not have to consciously do it for it to happen...it just does...and this happens without fail...I figure that this is the reason that I have a lot of stamina and that I am able to keep my pc tight for long periods of time without a problem when working it out..I was wondering if this happens to the rest of you guys out there...because my friend told me that whenever he masturbates or has sex with his girlfriend his pc muscle stays limp...

i was curious to this ? also because people say that u need to tighten the pc muscle but i have found that that makes me cum quicker. while experimenting i keep my pc muscle loose or not tense and i can last longer. i think that when we exercise it, we just gain more control over it, to loosen it to last longer (for me) or tighten it to ejaculate.

by clenching my PC muscle when i feel the tingling of orgasm it stops me from orgasming.

Oh and I think of my grandma, lol :)
