Look, in one's real life social circle rapport can be created and such relations can emerge organically, though the uglier the less likelier it is to happen. As people are basically forced to spend time together in many scenarios, and such can happen.

Yes there are some mentally ill sex addict women who do whore themselves out for free, but not only are they probably std filled, but their mental instability is likely an issue.
