I personally, find pregnancy disgusting. I've never understood why it's attractive. Oooh, a parasite that eventually turns into a baby inside a woman's body, squishing all the organs in odd ways, It's so hot. I especially get creeped out when people want me/others to touch their stomach or when people are practically chomping at the bit to do so. It's a basic biological function, it's not special or attractive, it's just there.
