I think the topic on slut shaming should also be addressed in this thread.
There is such a double standard when it comes to it. If a guy has sex with lots of chicks, then he's such a player/stud/whatever. But if a girl has lots of sex, she's a slut/skank/tramp/all those words in the book.
But having lots of sex isn't a bad thing imo. As long as it's safe sex, consensual, and no one is being hurt by it aka no one is cheating. Cheating is never good, and I would never condone it.
It's in my personal values not to have lots of sex partners and one night stands, and sex should be reserved for relationships when you really care about someone and trust them. But if my friends want to have sex with someone who wants to have sex with them, then cool. Good for them. That's their decision.
When people slut shame, it's really just dumb. They say to the person to have more self-respect. But the thing is that self-respect is exactly that. It's the respect someone has for themselves. Someone could have lots of sexual partners and still respect themself. One's own respect for themself is not defined by another person.
