I don't necessarily know a whole lot about what girls are attracted to...I only have my point of view and my sister's point of view, and both of us like boys who respect girls and treat them, well, nicely. Maybe you're right and the phrase 'nice guy' sets off non-sexy alarm bells...I'll change it. But in any case, the description isn't from Sally's point of view. When I say that he's a nice girl, what it means is that she doesn't find him threatening.
