I have no self confidence anymore.

Ever since having my son 2 years ago, I lost all comfort and confidence I had before (in my appearance). I have stretch marks, incision scar, belly pooch. My sex life is 100% struggling because of it. I’m never excited to have sex because I’m insecure the entire time. I stay covered up and won’t have sex in any position that shows the front half of my body. I don’t know how to get over this and improve things with my husband. He has got to be miserable over it by now. 😣
