Sex drive?

Did anyone absolutly just lose their sex drive after baby? I'm just never in the mood anymore, my husband watches alot of porn which doesn't bug me because ik its my fault for not being very intimate lately. I hate him seeing my body the way it is and its ultimately the most depressing thing ever, i gained 90 lbs while pregnant and ive lost 40 of it after 4 months but im still nowhere near where I use to be. I workout everyday but I also breastfeed so dieting is a little difficult at the moment. Has anyone else gone through something like this or am I just crazy?
