@Grahav: He got pretty well, how to analyze his situation. (Just gender swap everything.) By that logic he must have asked himself, what would happen if a highschool girl would whore herself out for that cheap. In the end nothing good. If his objective is sex, doing it for free and actively picking his partners is much better, then seeing what comes around. Also his chances for laying "premium" partners, who get enough game on their own, will drop drastically. Said premium girl/female jock would lose fans herself, if she is caught with him. Being a slut is still much better then being a highschool whore, selling herself for cheap. (Disclaimer: This is not meant as a jab at prostitutes.)
"In our world: To gain reputation guy must be chad lot while girls protect virginity (keys and locks)."
"What is interesting about that is that both of them may end with ruined reputations for having inverse morals in relation to that world."
Wow, I didn't see that, but your right. She might be looked as as the "dick/f." (that worlds equivalent of "pussy/m.") that chickens out, when talking to boys. That might totally ruin her reputation!
"Also, giving it away for free at random is also a reputation killer for women: "No one will buy the cows if you are giving the milk away for free.""
Nah, being paid for it wouldn't make that better. If he's walking the way of the slut, he might as well do it decently.
