I hate it when people generalize genders outside of physical evolutionary lines.
There isn't some kind of separate organ in the skulls of men as opposed to women: both genders are equipped with BRAINS, which work in vaguely the same way.
Lesbians sure can live without men ... though it seems to me that lots of gay men can't live without women. I'm a notorious hag, and all my boys seem to like it that way :3
