I would absolutely call a man a whore if he was doing the same thing. I'd also call him a skank. These words, to me at least, are gender-neutral. A whore is a whore. I'm sorry if you don't like the word, but in some cases it is accurate.
I don't like the word "moist," but sometimes it's the most accurate word to use.
Those words are not gender-neutral to begin with. Sorry. And I don't believe you when you say you'd call a man a whore or skank.
I don't care if you believe it or not. I would. I don't live in this crazy sexist world that a lot of people seem to.
