There's no such thing as biual. That's just something they invented in the 90's to sell hair products?

There was a study done in the US years ago called the kinsey report. On a scale of 1 to 10 students had to rate their uality, 1 being gay and 10 straight (or the other way round lol). most people were in the 2 to 9 bracket. Therefore is was deduced that the majority of people are to some degree.
