...donate your sperm? (or your eggs)?
I was discussing this with my mum the other day, and she said that she'd never donate her eggs, because she would always feel in some way responsible for the child that might be made.
I don't think it would it bother me at all. Even if I knew that there was someone out there that was technically 'my child', I don't think I'd think much of that. I guess the question is what matters most, nature or nurture?
In my opinion, your parents are the people you raise you, care for you, and love you. And genetics aren't overly important.
I'd consider giving sperm... I think there's some chance that I won't ever have kids, and it'd be nice to pass on some genes. Plus it would be helping people out who can't have children naturally. (And effectively it's getting paid to masturbate :p).
So what's your opinion on the matter? Would you give sperm/eggs? What's more important, nature or nurture?
