>>301217 said pretty much. People are also warned not to use drugs, gamble, or use social media and look where we're at. If you're decisions are easily manipulated by peer pressure then I guess figure that out first.
Also if you don't like casual sex and you learn it pretty early on through regret, you'd stop doing it, no? Much like a child who touches a hot stove top and learns that it probably shouldn't do that again, a woman, or man for that matter, who has casual sex and regrets it right after, won't want to do it again either. Unless you have some unresolved issues that you mask and pacify with the short term "feel good" reaction your brain gives you after meaningless shallow sex.
If you like being a whore and it brings you joy that a monogamous relationship won't bring you, then go hop on dicks, if you like you're boyfriend to not even look at other women, then go find a handsome golden retriever church goer.
Something something, everyone is different, everyone has to figure it out for themselves, you get the idea.
