How do you deal with crushes on straight people?
It depends on the straight person. I've crushed on a few straight guys who sorta figured it out with me saying it, and then they used it to banter with me and joke-flirt with me, which helped get them out of my system, even though it did make me like them more as friends. Some of them still give me banter about it, which is awesome lol
But I'm lucky, I doubt very much all straight guys would feel that way. Generally if you have a crush on someone who's straight, don't ever tell them because it could make things incredibly awkward between you. As Hybrid Trainer said, if it's just a crush find someone else to crush on lol
