Can people who are sexually attracted to each other be "just" friends? Not if one of them is a normal healthy male they can't.
So, faithful husbands are never attracted to their female friends? Are all women seducible (is that a word)?
If a man thinks you're hot, he'll eventually want to have sex with you. It's biology. The struggle to not act on those desires is sociology.
Actually it's psychology. Just because you want to have sex doesn't mean you'll act on it.
