Sex after a baby

I had my son 2 years ago. After I had him I started not feeling my self and not liking my body. As the time went by I still had the same feeling. I haven't felt my self since my son came. My husband is always wanting to have sex but I'm not comfortable doing anything. He is now thinking in cheating on him since I don't do anything.

Is there anything that I can do to get myself back into grove and start feeling good about you self again ? Please i need any advice I can get
