So, I just had sex for the first time last night and I guess my foreskin went back and it kinda hurt. Is it normal that my foreskin should go back like that? Also, I never had an orgasm last night and I woke up this morning and my foreskin was still pulled back. Is THAT normal?

I'm 16 yrs old and have just REALLY started watching porn. I am uncircumcised and in the videos the males can peel their skin back. But I can't. Is there something wrong with me or will this come with time / experience?
