Welcome to health class kids.
You don't know what you're talking about. For future reference, because I'm nice enough to do this:
Metroloveual = Man that is heteroloveual, but acts homoloveual.
Heteroloveual = Attraction the other love only.
Homoloveual = Attraction to the same love.
Biloveual = Attraction to both lovees. By the time you're 20, you will probably be biloveual. 1 in 3 people were biloveual as of 1990, as of 2010, I'm guessing it's more a 2 in 3 people are biloveual.
