Scared they might enjoy it.
I think it's mostly fear, repressed fear of rape and castration. Fear of rejection for lesbians. But don't generalise.
It's a thing they do when around their friends. Alone in public it'll be the same thing. But alone it'll be more subtle. Frankly I think straight guys just feel embarrassed
Because they believe it will somehow reflect on them. I don't know that they are afraid of gay but are afraid of being judged as gay themselves. Just my observations.
Backs to the wall LMAO
maybe they afre afraid of what is locked away within themselves?
maybe some hate,some don't like.
maybe they are uncomfortable or
