Post partum body

I don’t like my body after my baby. It’s been a year and 4 months since I had my baby and I thought I’d be more confident and comfortable in my skin. I seem to care a lot more now because I’m in a new relationship and we will eventually have sex but I can’t help and think what if he finds my lose skin gross and my stretch marks ugly. I also breastfed and now have saggy boobs and extra skin on the sides that I hate. What if he isn’t attracted to my body? Has anyone else felt like this? I just want to be beautiful again.
