AITAH for snooping on my boyfriends phone and finding OF activity that made me sad

I (25F) have gone through my boyfriend’s (25M) phone a few times in the years we have been together. Today, while he was fast asleep I got the urge to go snooping. I figured out that he made an OF account a few years ago (not active anymore) and DM’d a few girls paying for special content and even sending content of himself. I’m not judging that part, I don’t think corn consumption is the best but also don’t think it’s the worst. What bothered me was the timeline, he created the account just a few days after asking me to be his girlfriend, even one of the videos he took of himself he was wearing my cozy socks. I want to talk to him about this, and tell him that it hurts me that he would do this at such a good time in our relationship. I am obviously scared to admit I snooped that hard. What should I do? Get over it or talk it out?
