No feeling during sex

18 and I have sex about 8 times, and I still feel absolutely nothing. And every time I only feel pain in the beginning from where I’m super tight. I can feel him inside me but I don’t feel pleasure from it. Yet I get horny and want to keep doing it. I get pleasure from my clit, but never anything else. I still end up moaning, to fake the pleasure. Is there something wrong though?
