DH and I went out with some friends yesterday who are TTCAL after an ectopic. She and I were talking about advice we've gotten for TTC ("just relax", "get drunk and have sex" etc). Apparently a year ago she was out with some of our friends, and one of our friends' husbands leaned over and whispered to her..
"You know you have to do it in the butt first, before you can get pregnant, right?"
Needless to say, I don't think I will ever view that guy, or his wife, quite the same ever again. And now DH and I keep joking about "babymaking buttsex".
