Postpartum healing

Hi mommas. I decided to post here because I felt like I'd get the most support. I am 12 weeks postpartum now and I'm not sure if I should give myself more time to heal or say something to my doctor. I had a 2nd degree tear on the right side of my labia and it looks and feels the same as it was at my 6 week pp checkup. I want to have sex but don't look forward to it. Penetration isn't comfortable and even with lube I feel it gets irritated. Its naturally going to be rubbed against theres no way around that. I'm not sure if it healed right or if there's extra scar tissue or what. All I know is it's more sensitive in a negative way and it looks red and puffy sometimes. It looks different from the other side and I know it's not good to be the same as pre birth but it just doesn't seem right. There's no discharge or odor. I'm scared of having to have it cut and redone. What should I do?
