Hi - what a thoughtful question.
I wouldn't say "just willingly sleep with" men... In my perception, I'd say most single women are open to exploring, with the right person and in the right circumstance. And of course every single person wants something different. Some women like lots of gifts, others like popularity, others want a cathartic healing on some level (real psychological stuff). Some just want to not be bored. The only ones who want money from men are sugar babies and that is out of style like 2000s fashion.
