Sex after vaginal delivery

I’m 7.5 weeks post vaginal delivery. I had second degree tears during delivery and required an hour and a half of stitching after our baby was born. I’ve been cleared to have sex since 6 weeks, but I’m so terrified. I occasionally still have some pain, especially in the evenings or after I’ve done a workout/gone for a walk. I don’t know if I’m mentally ready to have sex because I’m so scared. My husband hasn’t been pushy or asking because he knows I’m worried about it, but I’m starting to feel like a terrible wife. Any tips or similar experiences?
