I love your pretence that it's not completely self evident to any English speaker and you aren't totally familiar with words such as slut, slag, whore, harridan, strumpet, bitch, hag, crone, cougar, floozie, chit, termagant, harpy, Karen, frump and so on. Yes, there are male gendered insults like dick, arsehole, fuckboy and cocklodger, but you know fine well that a) there are nowhere near as many b) they are not sexualised anywhere near as often as female ones and c) while a woman is a slag or slut, a man could easily be a stud or a lad. I can't, offhand, think of any word used to describe a sexually active woman as a positive, although I'm sure you'll be frantically Googling now.
And I love your pretence not to know that many female counterparts to male terms have devolved to have sexual elements like mistress and courtesan.
But since you ask so very nicely, I'll honour your disingenuous question and link you, as just the first hits I got, from Wikipedia. 26 pages for male gendered insults and 53 pages for female... and even a quick look will show you a pretty marked difference in tone between them. Please don't pretend you can't see that either.
As a quick addition, I also saw a number of pages dedicated to answering the question of why there are so many more gendered insults for women than men, so I think it's very fair to say that most people already know...
