It's also worth noting (or at least I think it is) that with arousal blood flow increases to various parts of the body in both sexes, & of course the heart rate increases to keep this supply up. Once saw a Desmond Morris documentary where they showed infrared footage of the process, with the lips, chests, loins, etc. swelling & warming; it was, um, interesting...& of course, very enlightening...

Lou, are you sure that is the same for all guys? For instance, I'm sitting here looking at your Av, concentrating....(THUD!!!!!)

The difference between male and female orgasms

Fun and educational. This thread made me think of this fun webpage.

I feel stretched and hard when erect, when really turned on it can feel it throbbing with my heart beat.

I just feel the throbbing desire to penetrate something warm and wet. :bj:

Oh wow! Very cool! Do you think that's time-lapse photography or can guys get hard that quickly? :)

Well I always wondered about the female orgasm as well. Or have we had this question before...? :spin:

Could use that one as a can opener.
