Sex still painful?

My LO is almost 10 months old, and I can’t figure out why sex is STILL painful! It feels like a slight stabbing or tearing pain unless we use a ton of lube or go reaaaaaaly slow. I never needed lube before having a baby and I’m frustrated feeling like it’s been almost 10 months and I’m not 100% healed. I only had second degree tears and needed a few stitches, so nothing crazy happened with the birth. Has anyone else dealt with this and if so any ideas?
