Hey all...I was wondering if anyone can guess a person's orientation?
As in know if someone is attracted to you or not, know if they're bi, or gay or straight etc?

I have a friend who has a habit of trying to guess people's orientation..she's like, he's gay, she'll go either way, he's straight, she's a lesbian but she makes out with guys...etc...would one have to know their own orientation before anyone else's? I haven't told her my orientation but I'm sure she's guessing? Maybe just to be nosy?
