There's simply nothing sexier than pregnancy. Just kidding. Pretty much everything is sexier than being pregnant. Like, I'm pretty sure a camel wearing sweatpants is hotter than I am in any given month of my pregnancy. It's hard to get in the mood when you're tired, and there is no fatigue like pregnancy fatigue. Growing humans is hard work, so partners, pay attention to this list of the most erotic things you should do for a sleep deprived pregnant woman.
I do not like to be touched when I am growing another human being inside my body. I have severe nausea and vomiting during my first trimester, and in the third, I feel about as attractive as an elephant seal. I don't experience the increase in energy and libido that many women do in the second trimester, either. The only thing I really want to do for those nine months is sleep. Between the constant need to pee and increasing discomfort (from back ache to wiggling baby to the thrombosed hemorrhoids I can feel between my butt cheeks), it's really hard to get the shut-eye I need. I would be beyond thrilled if my husband tried one of these erotic moves on me.
OK, so maybe I need to work on my definition of erotic. But I can pretty much guarantee that if you do these things, the pregnant woman in your life will get the rest she needs. (And that increases your chances of getting romantic with her by at least tenfold.)
