I've never heard anyone say "men prefer bitches"

Partially this is because men are less often the one whose preference is at the center of the relationship (the standard cultural trope is a man pursues a woman, attempting to make her prefer him) and so there is less scrutiny of men's preference by both parties, and much more scrutiny of women's preference by men (in order to understand better how to make a woman prefer him).

Partially this is also because male attraction is determined less strongly by personality, and the "bitch/jerk" adjective is about personality.
