Guess the question boils down to what you think people meant when they said that she'd be their first choice if they were gay...
First choice for what?
If it's just friendship, what's being gay have to do with it?
Frankly if I said "if I was to go gay Woll would be my first choice" I would talking about having sex with her. It would be my way of saying she's super hot, and I think being a bit round about and respectful, admiring etc.. in terminology is a helluva lot hotter than bluntly saying "I'd do her".
I don't know this person at all, I know her less than I know my usual "OMG HOT" focus who is in my avatar. She's just a photo. Why in the world would I be saying I would want to be her friend or be in a relationship with her based on a photo? All I have in those photos is a body so that's what I'd be responding to.
