WOW!

So a woman's body really isn't her own at all if a man can somehow partially own the medical procedures she undergoes.
Well I'm going to go and treat MY depression now by popping a pill in GF's mouth, and then I'm going to treat MY sleep apnea by putting her mask on, then I'll treat MY cramps by throwing her an advil.

Can I own the medical procedures of other people as well, or just my own GF? My mother had breast cancer and a double mastectomy last year--I guess that was that MY cancer and MY mastectomy. (I did after all suffer psychological pain from it. Who cares that it is her breasts that they chopped off right? I mean, my pain has to count too!)
Anyway, GF and I have talked about having children and since I have absolutely no interest in pregnancy or childbirth, she is going to have them. There has never been a question of my getting "an equal right" or "an equal say" or whatever in any decision she would make to terminate the pregnancy. (Of course, we can't have mistakes, so any pregnancy would be a planned one. But there are still lots of situations that might arise where terminating the pregnancy might come up.) Of course given our close relationship and the fact that we love and trust one another, GF and I would talk together about what to do. In the end though it is her body, not mine, and just like I would not accept her trying to dictate my medical decisions I would never try to dictate hers. As someone who can both get pregnant but also be in something like the usual male position regarding a pregnancy, I can't say I have much sympathy for all of the "shouldn't the man's opinion count"? My opinion should and will count inasmuch as my GF wants it to count. And really, I see no reason to ever stop and worry about how much she'll consider my opinion. Obviously since I'm going to have babies with her, I trust her to make good decisions. If I didn't trust her, why in the heck would I want to have a baby with her?!
In any case, since this whole conversation is a non-legal one (I assume it has to be since no one is willing to talk about tiebreakers, and obviously the law can't put that concern aside) it really just comes down to a personal decision about the kind of relationships to have. If you want a relationship the non-pregnant party gets to dictate what the pregnant party should do and owns the things that happen to her body then there are plenty of men who'd be happy to oblige (I'm sure they'll also want you barefoot, pregnant, making their dinner, and knowing your place--but have fun). If you want a relationship in which there is some vague "equal say" or in which the two of you have to agree about what to do regarding a pregnancy (I don't even know what that could possibly mean--you only get 12 weeks to decide to terminate a pregnancy in many states, so what happens on the last day of the 1st trimester when you're still screaming at each other in disagreement?

) you can find that too. Me I'm perfectly happy to be in a "my body, my decision" relationship, and in fact it's the only kind I would ever be in.
