I hate my postpartum body

I’m currently 3 months postpartum after my second beautiful baby boy. I’ve always been a bigger girl my whole life. My husband also has been a bigger man his whole life. Recently his job has had made him lose weight and tone up due to what it calls for. I love that he’s healthy but I feel like now we don’t have sex anymore because he’s not attracted to me. He always tells me I’m beautiful and he loves me but not being intimate has made my anxiety and own self doubt go into overdrive thinking I’m not good enough anymore. I just dont know what to do, I’m afraid to tell him I guess because I’m afraid he will tell me the answer I’m already thinking. Idk what to do, some advice would be amazing. I’m also already taking my mental health medication for

My postpartum depression.
