And I'm sure a lot more straight women have seen lesbian vids. They often talk about them
People are curious, doesn't mean anything more. Unless you're attracted to Men, then you're not gay.
A guy from school left a **** tab open (at his house) and it was 2 guys, one girl. Guys seems to be friendly too.
But he just didn't think anything of it. "The girl was hot"
Anyway, you'd be surprised what people are into and what doesn't bother them.
