I had a waterbirth with DS and am planning a homebirth with the next one. SO many times I've heard "Oh, I'd have loved a waterbirth, but DH wasn't keen" or "A homebirth? DP wouldn't let me do that".
I know that it takes two to make a baby, it's their child as well, etc, etc - but if it's you doing the giving birth, why should how they feel matter to the extent that it overrides the way you do?
