Blackpill of the day: Every oneitis you've EVER had has been fucked by other men while you rot.
I'm concerned about that train of thought. Are you talking about your own experience? Can you explain what you mean?
As I say to my friends, everyone is a slut. You just need to look around and you'll know that.
It's a pretty large and incorrect generalization to make that all women, everywhere, are promiscuous. Given that you mentioned terms like oneitis, you might have been spending a lot of time online in certain communities that dislike women and spread harmful ideas. I think it would be a really good idea to spend time away from the computer and more time interacting with people in person to see how women act in real life.
