no wen you are aving sex you pull your fore skin back how does it stay there and
what happens wen your balls drop :confused:
umm some peoples foreskin will stay back naturally with an erection because they have less skin. Some will move foward as its sliding in and out of a pussy or ass. The feeling of the foreskin rubbing back and forth on the glans is the reason why some people have orgasms.
as far as your balls dropping...i have no idea
my balls have never "dropped" during sex so I'm not sure what you're talking about
