According to Steven Pinker and his book, "The Blank Slate - The Modern Denial of Human Nature", morals (specifically sexual morals) come from the, "Darwinian economics of childbirth". What does this mean?
Basically, when a male and a female are considering getting together, the male is either lying about his willingness to care for the offspring (in many 3rd world countries like Honduras the dude just skips town . . . goes to a new village) or he is sincere . .. which will cost him years of toil. The female is risking using her finite reproductive process. These unavoidable factors are bound to have an effect, psychologically. If this danger response is indeed imprinted upon the human brain, then jokes about sex will always be funny. Sex will also always be a little, "dirty". If it were not, then it could be discussed openly at any time, and would be as, "funny" as a story where the humerous climax was eating a snickers bar. Null program . . . it's just a bunch of electricity in the pleasure center . .. but jokes about sex still trigger laughter.
It all boils down to food (for the baby), which is money, which, of course, is the root of all evil. That's procreational sex, baby.
