I've only ever been called a man whore once in my entire life. Had women think i were a cheater. That i cheated but was only called it once. And i didn't like it at all. Because i don't cheat, sleep around or have many partners. In fact it confused the hell out of me. I immediately turned into that meme of the woman with the numbers around her. Basically i was shocked anyone would ever say something like that about me. So this guy in particular did not take it as a compliment. And wouldn't.
Other than that. Most of what halcyondays said. Standards are different for women than they are with men. Which sucks and means less sex for men and women in general but that's what you get when society in general with that specific topic has the intelligence of oatmeal.
