Confused as hell

My boyfriend told me he wanted to me have sex with another guy to tell him the story of how me and the other guy had sex, it turns him on.

Well I told my friend and we were joking about telling my boyfriend that he was the guy I was going to have sex with

Well now I me and the guy are planning on it

My boyfriend knows and it okay with it

But Im starting to catch feelings or maybe it’s just the flirting I like Bc me and my boyfriend don’t really flirt any more.

Comments please!!! (Nice ones)
