How do you keep your hair from knotting up when on your back? (or am I the only one?) This is the first time since I was little that my hair has been past my shoulders and I really don't want to cut it. But every time after my husband and I have sex I look like I teased my hair to look like Snooki. Since giving birth missionary is the only position that doesn't hurt or feel awkward for me, so we really can't try other positions. I've tried putting my hair in a bun, which ends up with the rubber band so wrapped up in my hair I have to cut it out.
