A d for me. But I was probably more like an e at first and then worked Dh around. I think men don't really have a social/cultural framework for their role in birth (beyond waiting room scenes in movies or frantic driving) so they tend to err on the side of institutions and professionals. Now that Dh has seen me birth twice he knows it's more important that I am comfortable and have the support I need, as opposed to his comfort. In fact with ds birth I wanted to be alone. I love my Dh and I want him to be comfortable with the decision, but I do think the birthing woman has the majority of the say.
