Instead of the widely sexual beings we have the potential to be, we've been put (and put ourselves) into increasingly shrinking sexual categories. We are brought up to be "homosexual" or "heterosexual." As homosexuals, many of us become "leather queens," "bottoms" or "tops," "chicken queens," "dinge queens," etc. This boxiness makes us more isolated, seemingly foreign, highly specialized and limited sexual beings.
