The significance of autogynephilia in trans thinking and behavior is controversial. Some would say it's purely fetishistic behavior and doesn't indicate actual cross gender characteristics while others say it's common and exists in varying degrees for MTF people. In fact, one study intended to draw a line between autogynephilics and "true" trangender MTFs produced data that makes it very difficult that make that separation. Even GGs subjected to the same questions showed that half would be regarded as autogynephilic.
