In an ideal world people who just want casual sex would find each other. And people who want love as well. In an ideal world everyone would also have someone they are an ideal match to.
The only way I see people getting paid to have sex in an ideal world is if they get paid because their sex is so good, like top athletes.
We will never live in an ideal world, we can only approach it.
So, yeah, I wasnt referring to reality.
