If you don't want to have a long term relationship and just want something casual, to see multiple people, etc, then that is something you need to communicate and not cave into a relationship that you don't really want and waste everyone's time in a relationship that isn't really what you want.
Men often think that they need to fit into some "feminist" ideal (the man hating kind, not the equality kind). Who wants to be in a relationship with someone who hates themselves?
Too many men are approaching relationships from the "feminist" rulebook. That's a recipe for failure.
The solution is not to simply avoid women, it's to be honest with yourself about what you want and not put yourself in situations where you compromise your integrity.
