Porn Subscriptions

So, I’ve been dating my bf for 8 months and we just moved in together a month ago. Yesterday, I found out he had a Onlyfans account (porn site) that he had been hiding and using behind my back. He’s made multiple purchases on there buying videos or pictures from certain women throughout out relationship. He claims he only went on and touched himself when we fought and what not but I don’t believe that. I’ve explored many sexual things with him and out sex life is great. We both finish every single time and I’ve tried many things to satisfy him. I’m a good woman to him and have never stepped out of our relationship. I feel very upset and betrayed. Like everything he’s said was all a lie. I feel like I’ll never measure up to what the porn stars look like. He said I’ve done nothing wrong and that he gets very aroused every single time he touched me even if it’s just a kiss or holding hands but yet he went and paid to get nudes from other women. Why? Should I leave him? Is this normal? How do I get past this? Should I feel so hurt?
