I didn't stipulate that finding her attractive means you must think she's the most beautiful girl who ever lived. I also don't ask anyone if they fell in love with her at first sight. I simply mean sexually viable, as in, based purely on her physical appearance, assuming everything else about her met your standards, (whatever they may be) would you have sex with her?
This isn't entirely an academic question.
One time when I was gift shopping, I went into a Santa Fe-type place and was greeted by one of the most beautiful women I'd ever seen in my life. Apart from being gorgeous, she was also very warm and friendly -- when I came in, she looked at me and beamed this huge smile at me and said "Hi! It's great to see you!" as though I were her best friend that she hadn't seen in a year.
I don't normally do the pickup thing, but in this case, I decided to make an exception, so I started chatting with her. The end of the conversation went something like this:
Me: So is this a Summer job for you, then?
Her: Yeah, enough to cover expenses and stuff, you know.
Me: Definitely, I'm doing the same thing. So what are you, a junior?
Her: No, I'm a freshman.
Me: Ah. Have you decided on a major yet?
Her: No, not yet, I've got a little while to think about that.
Me: Yeah, that's true. So where do you go, George Mason University?
Her: No, Springfield High.
At this point, our eyes locked. Silence for several seconds, and then:
Me: You're a... freshman in, high school...?
Her, looking like she was about to bust a gut laughing because she knew perfectly well what I was up to: Mm--hmm!!!
Blink blink. Look around. Look at watch. "Wow, look at that. No wonder I'm so hungry, it's almost two o'clock. I'm going to go get something to eat. Bye!" I somehow managed not to leave skidmarks.
I was absolutely mortified at the time, although now that ten or fifteen million years have passed, I can see the humor in it. Now, though, I also see that it's informative and telling.
