I think you misunderstood the question. The question is not if people with hot bodies get laid more than others. It is whether they have better quality of sex when they do actually have sex.
oh, im really sorry for misunderstanding the question. I apologize. Hmm.. I think when a guy is in shape, he'll have increased levels of testosterone levels, and increased levels of testosterone levels triggers sex drive.. therefore, a healthy sex life.. just my opinion..it could be wrong.
