I (19F) regret exploring my boyfriend’s (23M) fetishes and I don’t know what to do.

TL;DR I regret exploring my boyfriend’s fetishes because he still watches other women and it makes me insecure.

Me (19F) and my boyfriend (23M) have been in a long distance relationship for a little over a year now and we saw each other about 2 months ago after almost 9 months apart. During those few days of us being together, I decided to play into his fetishes for the first time and he really enjoyed it. He has told me that I didn’t have to if I wasn’t comfortable doing so, but I assured him it was fine, even though the only reason I did it was because I’m very insecure and found out that he was still active on accounts, watching media related to said fetish and that made me very upset and insecure. I will not be revealing this fetish for his sake, but it is not vanilla and not something most people are into.

I found out about his fetishes a few months into our relationship after coming across accounts which share the same username as the one he uses on most other platforms. I asked him about it and he shamefully revealed that those were his accounts. I was initially quite disgusted and surprised but I have come to terms with it. One thing that has stuck with me is that he told me that he was “starting to lose interest in that stuff” or was “actively trying to stop browsing or watching related media”. Obviously that was a lie as I know that he has been active since yesterday the latest, although I also know that he has watched new artists/accounts months after I found those accounts.

When we met up, in addition to catering to his fetishes, I let him take photos/videos of me, hoping he’d actually stop watching other women in relation to his fetishes. I am extremely insecure and have low self-esteem; catering to these fetishes is the only way I could ever feel pretty to him. I have thought about asking him to delete my photos/videos, but with what he’s lied about, I don’t think I can trust him anymore unless I take his phone and delete those myself.

Do I stop catering to his fetishes? Or do I talk to him first about his account activity? If you’ve read this far, thank you for your time. Any advice would be greatly appreciated :)
