Uncomfortable sex

Every time I have sex with my fiancé, it’s uncomfortable. He doesn’t finish because I have to stop. I saw my gynecologist in August to talk to her about it and she examined me then gave me a new lube to try. I knew the lube wouldn’t help but I figured I would give it a try. It starts to hurts once he is about an inch or two inside of me.

It also is uncomfortable when putting a tampon in.

I’m not sure what it could be but I’m so tired of not being about to have sex without stopping. This has caused a lot of problems in our relationship.

Has anyone experienced uncomfortable sex?
