I’m not sure how to feel

My fiancé left his phone at home while he worked and I shamefully snooped. I found 2 females on his previously watched on tiktok, but it’s like he went on their account and watched every single video. I asked him about it and he said he jacked off to one of them.

The conversation before this tiktok was about him going on OnlyFans which I told him I was uncomfortable with. Im just really at loss for words and feelings. My head is everywhere right now.
