I think people are a lot more open and susceptible to trying new things. But I don't think confusion has anything to do with it.
I don't recognize "metro-sexual" as a valid sexual preference.
And I'm not 100% sure about my views on sexuality. The science behind the things that drive us to certain possibly discriminatory actions/choices has changed so much in a decade that I'm just not absolute in my belief.
In addition to that, unless I'm sexually involved with a person or have a thing for a person, I'm completely ignorant of gender and sexual advances.
