Non existent libido

Hello! Ever since having my second baby my libido has been at an all time low. I’m about 4 months PP. currently breastfeeding, I have endometriosis, and sex is painful still. I feel really bad because my husband is extremely sexual and he feels most loved with being intimate. But I’m literally at a point that even being touched or talked to in a sexual manner makes me feel sooo mad, grossed out and annoyed. I have zero desire for any orgasm or anything. Does anyone have any tips on getting my libido back up? It’s been taking such a toll on our relationship. I really want to desire him again but I don’t know how.
