Women don't usually put a lot of attention to men because they quickly assume it is for sex, and that can be very uncomfortable for women. Even if the woman finds the guy very hot and she has high interest in him, she expect him to take the bold steps. Women do use other methods such as looks, asking for favors, etc. so they are also active in attraction, but they don't really want to be seen as explicit. If the guy is autistic, of course this does not work, as the man has to do a lot of risky assumptions to advance that.

Men often have hobbies or activities to enjoy, not just sex, but they want to keep the 'manly' image by pretending they care about women or sex more than they actually do. Sure, men are hornier, but they pretend to be even hornier. Gays in the closet also do this more to keep the facade, but also heterosexual men, as sexuality is also status for men. This is very common among teen men, talking about the girls they supposedly fucked, even when obviously it is false most of the time.
