Responsible for giving one the ability to achieve a strong and through sexual performance? Is it the arms, the legs, the back, the abs, or the ass? I gots to go wit da ass (hence the reason for females checking out da mans ass in order to ASSess his potentional pumping power :> ) P.S. I read an article a few years back by a porn actor and he claimed that the abs are the main performer of the sexual act, and thats why he did 500 crunches on a daily basis LOL
