Discuss what? It sounds like another case of a man living how he pleases, this is obviously appealing to women as backed by the site.
It sounds like there's some more backstory here. You say there no hint of masculinity and that this guy's asexual. Do you mean asexual in the context that he never discuss's sex, or that he doesn't physically interact with other people---what I'm assuming you mean is that he doesn't project any sexuality, but he "looks good"
as you describe him and dresses well. Obviously this gets girls' attention and they respond sexually....
He might be obviously gay to you but if other don't know then they would think he's straight. Or he could be gay and it's just another case of a girl wanting what she can't have.
Girls respond real intensely to flamboyant guys as well as badasses....I can't gather enough info from your OP though it just sounds like a rant haha
ALSO
I know some some badass b!tches in choir...like seriously 16 y/olds with badass bodies sexy as fuk, and they've told me choir guys are attractive to them? If a dude sings he probably ain't that shy.
