Having no sex drive is normal as hormones can make things very strange indeed. Also areas down there are more sensitive because of the blood flow and sometimes things that used to feel good feel awful!
I know that my "woohoo" feels really strange at the present moment. Sensitive to touch and sometimes sore for no reason.

My Sex Drive is pretty non-existant (i'm having a Boy) but I am also finding that DH's Sex Drive is also non existant. I think being kicked in the guts by your unborn baby when your mid stride is a really big turn off for him (that's happened on more than one occasion!) I think also the positioning has to be different when pregnant which can throw a spanner in the works. I'm too big to be underneath which is where I prefer and I feel weird being ontop as I think that I am crushing him

So to sum up, its perfectly normal to feel the way you feel!
