Confused. Porn

Jasmine

So me and my partner/ friend were talking. He’s Mexican and I’m black. And I was telling him that lately I’ve really been into watching porn with Mexican men. Which I have lol. Last few years I’ve been hooked on them haha. But anyway He says “oh I don’t want you looking at other men”.... “just me”. It threw me off because he knows I watch porn. He does too. We’ve discussed the type of porn we watch so I didn’t think it was an issue me telling Him that because we’ve had an open discussion about it. I’m just puzzled as to what changed. I thought we were on the level to discuss that like we’ve done before.
