Body confidence & wanting him to want me!

I just gave birth to my daughter 3 months ago. Since then I have been so self conscious of my body, especially down south. I have stretch marks in places I'd never thought I could get them, hemorrhoids 😢, and my V looks nothing like it used to. My husband won't even go down on me anymore. He hasn't said anything about my appearance yet but I can just see it on his face. To add to my confidence issues my husband doesn't ever want to have sex with me. Once maybe twice every 2-4 weeks if I am lucky and the rest of the time I'm being shot down or having to tell him I need to have sex. We have fought more now since I've given birth then we ever did and I'm finding it hard to keep going on without feeling wanted, loved, needed or sexy. He is military so he can get very stressed and tired from work but every time I try to initiate anything he will just sit on his phone or barely put in any effort to even kiss me. I just don't know what to do anymore.
