Straight men, what's the weirdest thing you've been told you can't do because it's gay?

Dance. In a troupe full of girls. Honestly, it was me and 15-20 girls.

Other boys literally called me gay for dancing, while they went and played whatever sports they did and then all went into a locker room and showered together etc.

I honestly never understood how they thought dance was gay. I don't understand it now.
