Just because you don't like having sex with different people doesn't mean you are a better person and just because you like having sex with different people doesn't mean you are a lesser person. Slut is a slur that humiliates people just because they don't meet your personal preferences, as long as everything is between consenting adults there's nothing wrong in exploring your sexsuality and having fun. If we don't shame people for not having sex or having only one partner we shouldn't shame people who like sleeping freely with different people.
I'm not saying anyone is better or worse based on that. I'm talking about a fictional character and how his behavior is written in the story. i used ‘slut’ to describe the character's pattern of repeatedly sleeping with different people as portrayed. i understand your point, but i think that kind of behavior can be criticized in the context of how the character is portrayed in the story.

why can't the ml just stop being a whore, their sex is great—good chemistry. but the ml is such a slut.
