No you are not.. When I was pregnant with my son *who is now 8mo. old* I had forgotten what sex was and since I wasnt ... ever in the mood for it I for some reason just expected my hubby wouldnt want it either... until he talked to me about it and I realized that my drive just went to NIL... there are ways to just get into the mood, you might not be IN the mood but you can try to get there, just dont THINK about getting there be spontainous.. I tell you what though 2 weeks after I had my son, you can't have sex for atleast 6weeks at the most, or until your body feels safe to, my hormones shot thru the roof after the budle of joy was out of my body. You lose that drive because your body achieved the reason for wanting sex, reproduction. Atleast thats what I explained to my husband and it made sense to him, it's not from a doctors mouth, but its the truth. When you are fertile your drive is through the roof.. but anyhow.. You are not alone, the best thing to do is just keep trying different things, and know that it is NOT permanant, your drive will come back. My hub thought it wasnt going to and well its back with a vengance
Best of wish and congradulations!
