I generally don't think that sex difference is particularly interesting. Things like truth, politics, beauty interest me more, if one can say that without getting a slap for being pretentious!
On the other hand, in certain things I do (work in a philosophy department in which I am the only female PhD student out of about 20 total) I do increasingly want there to be more women around. Not because I think they'll have a specific effect, one way or another, but partly just because it seems weird to always be the odd one out and for the situation to be so unbalanced (just why don't more women do philosophy anyway? Are they all off doing better-paid things?! Hmmm).
But I would say that I am more of a bad cliche of a 'man' than most of my male friends! Belligerent, insulting, often drunk, horribly objectifying towards other women, etc. So, er, yeah. It's complicated.
