'crazy person'? That's just rude.
Since the 1960s, when contraception became revolutionised by The Pill, sex has been more about recreation than it has procreation. It's a multi-billon dollar industry, the sex industry in USA has regulations, medical restrictions etc to keep everyone healthy. If this young lady wants to make a living from her body while she can, who are you to call her crazy?
My husband was a miner. He went underground, in dangerous conditions for a living. This kind of living seems more profitable and WAY more fun... Crazy? Crazy is as crazy does...
