This is a hard one. On the one hand I do agree that because you are the one doing all the work, and because it is YOUR birth experience, you should have it the way you want it.
On the other hand, I don't think at any time in a marriage, one should adopt the attitude of, " it's my body, this is the way it's gonna be, so deal with it."
there needs to be some graciousness. Let him do his research. Keep talking to him about it in love and patience.
