#3, natural curiosity doesn't constitute "fascination". I'm sure you are well indoctrinated in the American Way of being ashamed of genitalia, as well as stopping yourself from learning things even when they're of uncommon experience, but your demented restrictions are not to be admired or imitated. The social gayness that you exude is supposed to have died back in the Dr. Kinsey era.
