TMI !

Okay ladies this maybe way more then you'd want to hear but I have to speak on this because I am confused! Well all of my life I have never had a "horny bone" in my body (yes, my husband married me any way lol) 2nd trimester when supposedly we're supposed to be really horny it never happened for me (poor hubby) but at 33 weeks I have been extremely horny ! Am I the only one? Is there an explanation?
