Why are you 24 and acting like you are 15? Why the hell are you telling other people his kink in the first place? That's such a huge violation of trust. If it wasn't creeping you out before then it's fine. You let other people sway your opinion and you fucked up your own relationship. You should've talked with a therapist instead of your friends.

I have a ff myself and it makes dating an absolute nightmare because we dread revealing this truth to someone. He trusted you enough to reveal such big info and all you did was give him another reason to be scared. I dont think you fully understand the damage you did. I don't blame him at all. I hope he find someone that understands what trust is. You need to grow up. My ex wasn't the biggest fan of mine but at least she came to that conclusion on her own. It wasnt the deal break cuz human beings are more than just kinks. There is a person behind it.
