What is Gender Good For

So this article asks 'what are men good for', of course the author was asking it on the level of sociological gender differences, but I found myself last night asking 'what are women good for' on a personal level. Aside from my sexuality, I am not sure it matters to me whether a woman is a woman or a man. Surely the fact of a person's gender is part of the mental frame through which I interact with that person; it's part of the mental frame through which they interact with the world, just as it is part of mine.

I think I am uxorious because my wife is the person she is, and happens to be a woman; if she were a man, she'd either be my best friend or I'd need a different word than uxorious to describe myself and a different phrase to describe our relationship than 'female led'. (I am so not an apologist for female led relationships.)

So I sincerely wonder, on a personal level, after one's sexuality is discounted, is gender merely a part of my social reference frame, and then not even a very important part? What is gender good for? To what extent have we managed, will we ever manage, to surpass our gendered evolution? Does it matter?
