> Right but the use of men by women is almost always negative and dehumanizing.

I'm 30 and I haven't seen this be the case anywhere ever.

I have encountered some people who condescendingly use "boys" when they want to disparage adult men. It's always bugged me even when I was a teenager, although for some reason all the gay men I know use it. I think a similar dynamic exists with women and "girls".

I find myself using "female" occasionally, not to refer to women I would date but because English doesn't have another good word for "feminine humans of an indeterminate age". I occasionally use "chicks" for similar reasons.
