Sex after childbirth

I’m 3 months pp and I’ve had sex only three times since birth because it hurts so much. My husband says I’m wet during foreplay, but I don’t feel like I am. Then when I try to get on, it takes forever to feel somewhat comfortable but it still hurts way more than usual. I did have a 3rd degree tear that required stitches and my sex drive is very low which is frustrating because my husband thinks it has to do with him and it doesn’t. How long did it take for sex not to hurt anymore? Any other tips?
