I voted yes. (Which is the leading answer in the poll, though you wouldn't know it from reading the thread). I think, like ila, if things had progressed to the point where we were having sex I'd already have some feelings for her. (I am personally not really looking for a one night stand at this point in my life). I'd also have to be attracted to her in more than just a physical sense (and I no male model here so I am guessing she'd feel the same!)
I like your answer, jimnaseum.

I myself am looking for a soulmate, I am too old to be "sport fucking."
Bionca, there are some pretty callous answers here, I agree. Too bad some people don't seem to want to educate themselves even given the opportunity to do so.
