Well, I don’t see these used around as often as the female equivalents, and some are more compliments. Like womanizer is to describe a man who charms women. I have heard of fuckboy though, but it still isn’t used as much. For example, people in these replies are already making misogynistic comments. However I don’t see any misandristic comments anywhere when men describe their issues. Also simp is a popular one, but again doesn’t relate to anything sexual. It’s like women who have sex are disgusting

Agreed. Like you said, half of them are compliments and something men aspire to.  Others like man-whore are modern and rely on the misogynistic definition of whore in the first place. 

Others like fratboy simply mean someone who is in a frat. 

A fuckboy doesn't fit the bill either.
