Gay friendly? meaning?

[Camfer]

Maybe he had never seen or heard of gays before.

A friend told me, today, that he was terrified of meeting me. We had been playing games online together for years, but finally met irl half a year ago. He knew I was gay etc., and he had never met a homo. pretty weird huh

I think you're right, that he never imagined that two grown men would ever sleep in the same bed together, and that he'd never thought about gays at all. It seems astounding to me, but definitely possible.
