Pain after sex

Me and my boyfriend that i have been with for over 2 years ❤️and we recently started having sex we decided to lose our virginity’s to each other but I was in so much pain which is normal for your first time but our 2nd time came and 3rd time as well I was still hurting I just need to know if that’s normal cuz I don’t think it supposed to still hurt but since I don’t have much experience with that I’d like some advice
