what do I (18f) do after finding explicit content in boyfriends (19m) activity feed?

for some background context, him and i have been dating for about a year, we have both been cheated on in the past, so there is some mutual understanding and respect to each others boundaries.

kind of early on in the relationship, i had found a boatload of messages and insta reels between him and friends, that were sent not too long before we met, of suggestive and sexual content of specifically alt girls with dark hair and alt makeup/clothing. this did bother me, but i acknowledged that him and i didn't know each other, so to leave it at that. it just honestly hurt and left an impression since i'm not alt or look anything like "his type", which he denies having but at the same time admits that "im his type" because i have dark hair.

today i was using his facebook marketplace to search for stuff, but noticed a lot of the suggested reels on his homepage were very sexual and suggestive. i maybe shouldn't have but i went through the "activity log", and found a handful of them that said they were "watched". which from testing it out, you would have to watch at least half the video, it is not like scrolling through tiktok and the videos you scrolled past or watched for three seconds appear in your history.

i don't know what to do because i feel that i have talked about this with him too many times, not about this specifically but just what happened in the past and him recently liking reels of biker girls on instagram. it is also partially on me for being nosy and looking into his business, but now that i've seen it i don't know what to do going forward, or if he even intentionally watched those all the way through.
