For me it's much more about personality and style than it is gender usually. It does seem to feel a little different though.

I have frequently brought up vaginas with my male therapist, which is a bit awkward. It's relevant though, so I do it anyway. He's OK about it, but it does seem that he has trouble relating maybe. He tries though. Everyone has a mother and father though (at least biologically), so I would think that it wouldn't be unusual to talk about mothers or fathers with either gender.
