Uncircumcised sex talk

It’s my (23 F) first time having sex with an uncircumcised male (23 M) we just recently started dating and he is a virgin.

We tried having sex but it just wouldn’t go inside. I was very well lubricated however it would hurt him since the foreskin would pull back.

Is that normal to happen?

Any tips for my first time with an uncircumcised male? Because I am LOST AF.

We’ve tried 3-4 times now and nothing seems to help and we both are doing research to figure out how to make this work lol since we both are eager to have sex with each other but it just doesn’t go in without hurting.
