I don't think you'll get many answers tbh. This is the coli after all, where dudes bring up old shyt in unrelated topics.Doing a personal survey. That's all.
Having said that, I've never had to sell ass or thought about it. I couldn't imagine constantly having sex with random men. Who cares if it's for money. Your adding unnecessary miles.
Also afaik none of the women I know have had sex with someone because they fell on hard times. But then again would they tell me?
