Those things appeared in gay media a thousand times before CMBYN, it's quite a common aesthetic for gay films, second, the 80s is a style that is very on trend nowadays and given that the movie is about HIV anmongst other things I can see it as a reference to the start of it all. Bikes and smoking have appeared both in several gay films and short films through the years, like "Kiss me softly" for example. And Troye wants to fuck Tim as everybody else lol, I don't see why is this even a theme to discuss in here. CMBYN didn't invent that aesthetic nor was the first film piece to ever have scenes like that
