Why are some people more sexually driven than others?

Genes and morality: Traits are passed on through the combination of billions of base pairs that are arranged in a unique order on our DNA, half from Mom and half from Dad. so each of us is one of a kind yet still enough alike to combine our DNA to make another completely unique human. Many evolutionary forces affect sex drive and our attitude about sex, which is taught, affects how we harness (or not) that drive.
