2nd trimester sex (maybe TMI)

Mal
Although sex is not uncomfortable for me I struggle with having zero sex drive. I'm 17 weeks and have to convince and talk myself into initiating sex. My husband is amazing and doesn't try to initiate anything since I was so miserable for the first few months. He rubs my back and cuddles with me but unless I take it any further he will just lay there until I fall asleep. Unfortunately even when I can get myself talked into it I just can't enjoy it like I used to and it frustrates me to no end. (I know it's TMI but I find that I can't "O" at all while having sex at the moment, maybe because I'm not totally into it at that time??) Whatever is going on I sure can't wait for it to pass so we can enjoy the great pregnancy sex everyone talks about in their 2nd trimester!
