What morality is involved in human natural inclination for sex that was not put there by other humans? Consensual sex is the same as eating or going to the bathroom. A natural instinct with a very strong urge to encourage perpetuation of a species. It is fun for that reason.

Humans have been successful on the earth because they have reproduced in the millions. I am not saying there is not a reason to avoid promiscuity unwanted pregnancy, and disease being a couple of reasons, but even then, it is not morality. What is the significance of a person's lack of having had sex? Zero. What is morality if not invented by religion?

Culture, religion, society, jealous people who can't get laid and hate others who do are some of the reasons. What is called virginity deals in ownership and perceived value. Then pushing that value on others by way of laws or social coercion.
