I was on Ivillage looking at my pregnancy calendar and i was reading all the way into week 17 and came across this..
Beyond hormonal changes, some men worry that they might hurt the fetus or that the fetus might be watching them while having sex (all untrue, but nevertheless not very arousing notions). Men can be unsettled by the realization that sex is for making babies, and breasts are for feeding them. Plus, because of hormonal changes, your vagina is darker-colored, has more discharge, smells different, and has more hair, which may make your partner feel like someone snuck in and redecorated his favorite room in the house.
OMGosh, I had to crack up that they even put that in there. Thats like something a guy would call it.
