I've been hearing a lot about getting paid for egg donation (is it still a donation? isn't it more like a sale?) and it might be something to think about. It helps people who can't have children otherwise (although I kind of think they should adopt) and if I have double the amount of an average woman, so it wouldn't really hinder anything with my own future children.
But I don't know if I would be okay thinking that there are little people with my DNA running around that I don't even know about.
