Sex with anti-choicers?

A girl recently wrote to sex advice columnist Dan Savage asking if it was morally correct for her to have sex with her anti-choice boyfriend. Guess this was too racy for The Ethicist:
Q. My boyfriend and I are 18, and we’re in love. We’ve been together for almost four years. He recently decided that he is against abortion, to the point where he won’t have sex with me unless I agree to have the kid if I get pregnant. I told him there’s no way I can agree to that. It’s my choice what I want to do with my body, but he says it’s his choice if he wants to stop having sex with me because he disagrees with my views on the matter. (Which is something he read in your column, BTW.) Where do I go from here? I can’t be celibate until I’m ready to have a kid. But I don’t want to break up with someone I love because of a sincere moral disagreement. What now? —ONE BOY’S GIRL YEARNS NERVOUSLY
A. As a general rule, OBGYN, fertile pro-choice girls shouldn’t have premarital sex with controlling anti-choice boys. But you love him, and sometimes love makes exceptions. So if you do stay with him, and you agree and/or pretend to agree to his conditions, and you get pregnant, and you do decide to have an abortion, what the hell is he going to do about it? Lock you in the trunk of his car for nine months? Whatever you tell him now, it will still be your body and your choice then. Use condoms, take the pill, get a diaphragm, cross your fingers, and fuck his brains out.
I say sex with anti-choice folks is out of the question. No exceptions.
Thoughts? Anyone ever venture to the dark side?
