Painful Sex Almost 6 Months PP? TMI

M

We have only had sex twice since I gave birth once at 12 weeks pp and once last week at 5 months pp. Both times during entry it was pretty painful like hot knives. We used lube but it didn't help at all. I did have a second degree tear and a pretty good scar. We were able to have sex and have it feel good eventually but initially it hurt alot. Is this normal thinking I shoukd check in with my doctor although I'm sure there isn't much they can do. I'm also breastfeeding if that makes a difference.
