Eh, I'm torn. On one hand, I don't think it's possible to be
in love with somebody without identifying with a certain sexuality (if you're a guy in love with a guy, you're gay if not bisexual). But then I think that purely mental (not physical) love can also exist. I've witnessed it, but to a lessor extent. I've known people who were deeply in love but not sexually attracted to each other whatsoever.
But that's cool for them.
