How does stage gay stuff even happen

I’m really confused as to how the whole stage gay thing happens… like does it just happen in the moment or is there like a band meeting or something?

I mean can you really go up to your fellow band mate and be like, “hey, so we should kiss on stage and you should rub your dick on me and I should act out giving you a blowjob, you know for the fans.” I mean how does this shit happen? I wanna know! I mean they don’t have to go along with fan ships but I know that’s how some start but what about all the kissing, and acting out sex and they must still get horny, how is it not awkward?

I wanna know how this shit works!!
