Dear David, I know you didn't mention homosexuals. That is my point. You have overlooked something.
Homosexual men look just like heterosexual men.
You, probably like most people, assuming some one is heterosexual by default. If you are discussing Sex then just what the orientation of a person is important. I realize this is new territory for you. Well if he's a hair-dressing wearing a dress and flirts with men then even I can figure out that one. But not all homosexual men are of the effeminate type.
