I know there won't be much market for it.
There are so many factors feeding into our responses it's difficult to single them out. And I'm not even going to comment on Cosmo. Not going to do it. Not even a little. Okay, maybe a little- no, not going to do it.
I think as women are encouraged (be it by nature or conditioning) to spend more time with their appearance, they are more willing to look at other women than men are at other men. And there are some theories about dominance as it relates to the sexes and watching, displaying the body, etc. But I'm not going there.
And then there's the stuff we've just learned to tolerate, as until recently women SF&F fans were in the minority.
