Advice?

Hey guys ! So me and the guy I’ve been dating has been talking about trying a 3some lol. So we were otp today and he says “ bae no offense but I never been with a white girl I wanna see what it’s like to have sex with one “ then he mentioned that some white Girl was trying to talk to him so then he goes on and ask me if I wanted to have a 3 with her. I really feel some type of way about the fact that he asked me to have a 3some with a girl that been trying to mess with him. So many things are running through my mind .... Advice and am I being childish or over thinking
