When should I come out to my friends

I wanna come out to my friends but I wanna keep making gay jokes (their not homophobic) but if they now I’m bi and make gay jokes I feel like they won’t know if I’m joking or not also I know they’d except me but I just don’t want the dynamic to change and I’m actually pretty sure they think I’m gay whenever they ask (they do ask) my poker face is actually trash.
