Feel like a virgin

Tonight my so and I tried to have sex for the first time since the baby. I was supposed to have a vaginal birth but due to complications I ended up with an emergency C-section. Tonight we were so excited to have sex for the first time since we finally got cleared to. I kept making jokes about how I feel like a virgin ( I know that's not how that works, also we've gone longer periods of time without having sex when he would go on deployment) . When it came down to it everything was going well my husband made me feel sexy and when he goes to put it in it was super tight. Straight up felt like how it did when I lost my virginity at 18. He was going slow and finally once it was in he continued to go slow since I explained it hurt/ kinda burned I think from stretching. We tried different positions and eventually I asked to stop because it was more uncomfortable instead of enjoyable. My husband of course had no problem with stopping (he's very respectful and knows Ive had sexual trauma in the past so he does his best to make sure I'm always comfortable) I immediately started to cry because I felt so bad that we both wanted it and because of how it felt I told him to stop so I ruined the moment. And I felt even more awful because I know I'm so lucky to have such a patient and understanding husband. We looked forward to the moment the entire 6 weeks and especially all day just for us to not be able to finish and me hurt. Has this happened to anyone else? Is it supposed to be this uncomfortable the first time after having a baby? We were going to try again tomorrow I'm hoping it goes well.
