Self esteem after pregnancy

My daughter is a little over a month, my SO & I haven't had sex yet because I'd like to wait until my 6wk appt. I went from flat stomach, size 0 jeans, & 107 Ibs pre pregnancy to 156Ibs when I delivered my LO 😬. I'm down to 130Ibs now with a small tummy pouch but quite a bit of stretch marks (plan on working out to get to 115 & loosing my stomach). I feel extremely self conscious about my postpartum body & how my SO will feel/see me (he hasn't seen me naked since having the baby). He wants to have sex but I still haven't accepted my body & I know he prefers toned bodies like how I was before. Anyone else self conscious or have advice?

Picture below is my goal, my body at around 9wks pregnant.
