Most Helpful Girl
I definitely do in most conversations, even to people I'm not one but attracted to.
I'm pretty sure that most people, in most conversations with the opposite gender, think "I wonder if they're attracted to me." It's built into us. There's always natural tension. Us girls want to be admired (physically) so I think that's a big aspect for us---thinking "Do they think I'm pretty?"6

Wow the girl in the pic that was added by a mod looks so annoying. But I think this relatively often if the person shows some kind of signs that they're attracted to me, it just makes me curious. I never mention it to them though because I don't want them to get any impression that I feel the same way.2
