am i the only one that experiences REALLY REALLY bad pain after sex?

whenever my boyfriend and i have sex, the experience is great but afterwards i’m in such terrible pain (burning, or like something inside me is ripping?) for about thirty mins for two hours and it’s so bad that i can’t walk or move and he has to carry me. we’ve tried more lube, lots of foreplay, everything and nothing’s helping. it’s very difficult for me to schedule an obgyn appointment at the moment and the internet isn’t helping me at all and i don’t know what to do. it’s seriously ruining both of our sex lives and it makes me absolutely miserable. does anyone know what this might be?

(i’m sixteen, could that be a factor? i know that that’s young but i really want answers, i just want to be safe and healthy)
