Re: sperm - Oh jeez, no, I could never ask someone to make that kind of commitment. And even though he wouldn't have to be involved in the kid's life, it would still be a commitment, because he'd spend the rest of his life knowing that this kid was his. And I'd know, and the kid would have to know, and I don't want to complicate anyone's life in that way.

Nope, going the anonymous route.
