Myth It depends on the person. You can usually get a hint of it based on the way they speak or dress, but sometimes it's hard to tell. But to be fair, I did go to college in a very pro lgbtq+ place, wo everyone there was fruity in some manner.
Myth I have a freakishly similar story where a guy I vaguely liked hit me in the nose with a dodgeball- he came to see if I was ok and it was the most awkward thing in my life- so awkward I am now a pro at deflecting flying objects to prevent that from ever happening again LOL
