The natural states of healthy human beings, male or female, are virgins or parents. When people try to act is if its otherwise, things go wrong.Precisely ma'am. As for the authority behind that, see either the Christian orthodox view of same, or for the heathens/pagans and others here, observe Natural Law and the results of denying same versus the results of not.
One really only needs basic biology to reach my conclusion. Human beings are born virgins and remain virgins until they have sex. Once they have sex - if they do it in a natural way - they will quickly become parents, if they are healthy.
