two different issues here
OK, if you really want to do this right, you should have two different threads with voting buttons:
1) Who wants to LOOK/DRESS pregnant?
2) Who wants to actually carry and have a baby?
Personally, my SO and I have talked about this many times. We have both decided that we are so nearly gender-neutral that our lives wouldn't have been much different had I been the man and he the woman. He tells me he frequently dreams of having a baby, and if there were one thing I could do for him I would let him have that experience. I think he really means it; it has nothing to do with clothing or passing or anything else. He is truly a man that was meant to be a mother, and that is just one of the many reasons I love him so dearly.
