Insecurity about body after pregnancy

Please no rude comments. I am trying to learn to love myself.

So I had my second kid and this time my body took a big toll. Its left me very insecure and I don't want my husband to see me naked anymore. I started exercising again and using products to help my streched skin. My husband just blows up on me and doesn't understand why I hate myself. What I don't understand is that he constantly looks at fit women with the nice sized breasts and butts. Even makes a noise when he sees one he really likes. I have saggy boobs and saggy everything. How can he say I'm attractive when I look nothing like the women he looks at? I just want him to stop lying. Help me understand and ways to get over my issues.
