I love the Huffington Post. I love the way they write headlines that you immediately feel you need to rush to read. This one came up on my feed yesterday – Can Sex Cure Morning Sickness? Of course I had to go read it. Holy crap it was technical but the gist that I was getting? Your partners semen is a foreign substance in your body so you treat it like a virus and are try to get rid of it. So the more sex you have at the beginning? The more your body gets used to your husbands semen and the less sick you are.
