Sorry to say this, but I'm a little disappointed in you girls, implying that being gay would somehow make Juan less of a man. That's simply not true.
I'm sure he isn't gay (any suggestions otherwise would be uninformed and speculative), but is reacting to someone's curiousity in such a negative way really necessary? Lots of gay men just want to relate to someone they admire and I know where they're coming from. I don't think that's a crime.
I was just replying with a pick of humor..
