The OP is a female so this isn't misogynistic in a conventional sense.
I'm married; I've deduced that women think about sex way more than men do. Most women don't talk about their sexual thoughts freely outside of their own close (same sex) social niche. I got lucky, but I'm curious about what must the OP have been thinking before the inspiration to write this thread?
My personal opinion is this: Even though the act of selling sex is dangerous and borderline self-destructive; it's nobody elses' business. Trading sex for Bitcoin, cash, car repair, groceries, or whatever is of little importance to those not involved. The relationship between the people having sex is the important factor. Having sex with somebody you don't know isn't the same as sleeping with a person with whom you share a metaphysical attraction. Trading sex for goods/services is blind and dangerous; using sex in a relationship to leverage goods/services isn't the same game. It seriously detracts from any relationship, but it's not as much about sex as it is about dominance.
Who hasn't hooked up with somebody they just met that day? I bet there aren't too many grown adults who haven't in this day and age... Is the desire for money so much different from the desire for sex? If you have sex just for the sake of having sex; is that not fulfilling the same psychological desire?
