Sex for the first time

I am going on 4 months PP and just barely getting my sex drive back. I felt comfortable enough and ready to try having sex with hubby a couple nights ago (yay!) so we tried and.... it wouldn’t go in. Lol😩 I had a 2nd degree internal tear along with one on my perineum and they are both completely healed but tbh I was very nervous to have sex again cause I was afraid I would rip back open where I was stitched (unrealistic I know) so I admit I wasn’t 100% relaxed and I’m sure that was part of our issue but I wasn’t expecting it to just not go in😂 we tried with fingers first and that felt normal so I figured the next step would be easy and painless but it was literally like losing my virginity all over again and my hubby even said “it’s like the doctor stitched you up tighter” lol I felt so bad cause my hubby has been so patient with me (last time we had sex I was 6 months pregnant) so I was just wondering if anyone else has had this problem and if anyone has any advice for me or if I just need to suck it up🙃

Also I should mention at my 6wk check up my doctor noticed that I had “over healed” as she put it and created more tissue than I should’ve so she cauterized it and said all should be good. She also mentioned that if that tissue were still there sex would be uncomfortable. SO with that being said I’m also wondering if I should call and ask her about it or if me and hubs should try a couple more times first.
