I actually used to talk about this back in the good old days with my friends.
I used to have a little sister fetish back in years 8-10, and I used to ask one of my friends if he's every had improper thourhgts about his sister. I used to ask him if he fucked his sister's friends etc.
I was once ranting about Asian girls in math class, and my friend said that he knew and played valorant with an Asian girl in his tutoring class. I spent the last few weeks of school talking about how much I wanted to fuck his freind, and I asked him questions like how big her boobs were, and hot tight her pussy was, and her favourte sex position etc. I believe that was our final conversation. Knew this guy since yaer 7, and our final conversation was about his asian friend lol
Eventually it got ot the point where if I even mentioned her, he'd go to the other side of teh classroom.
And I once had an arugment with a chinese friend about whether a girl was Indian or Chinese. We eventually settled with half Indian half CHinese, and I ranted about how much I wanted ot fuck her. I found her tiktok by pure chance, and told her I found her tinder account, after which she removed my comment
