What no one talks about after the baby

The relationship changes, things become to different and you question if you all even need to be together.. my question is how do you get past this?? What can I do to bring back the “happiness” and especially the sex life, idk about anyone else but I have a 2 month old and my man has had sex with me twice since he’s been born.. I feel awful about my body and like he doesn’t want me but he says that’s not it so idk.. I just need some advice to get over this bump and please don’t say just talk to him because I’m not even sure what to say
