metrosexual isn't referring to sexual orientation. It is a subcategory of heterosexual but the fact that it has "sexual" as the suffix leaves some to believe that there are some gay connotations to it. I, for one, think the whole introduction of a special sexuality to embrace men who take care of themselves is absolute crap. I'm the most gay-knowledge filled straight guy u will ever encounter but even I would feel awkward being labeled metrosexual.
