Of all the alarming and deeply inexplicable aspects of becoming a new mother, the one I found most unnerving was the way strangers began suddenly asking about my sex life. For 35 blissful years, no one but me (and, to varying degrees, my partners) seemed remotely interested in the state of my libido. And then suddenly, only a few months after I’d gained a third of my body weight and experienced the joy of a small human driving a Mack truck through my pelvic floor, everyone was suddenly going on about it—doctors, midwives, friends, family members and the media (news outlets in general, but women’s magazines and mom bloggers in particular). Looking back, the questions started in late pregnancy: Did I want it more? Did I want it less? Was I dreaming about it? Was my vulva swollen like a grapefruit? Had I watched the YouTube video of that woman having an orgasm water birth?
