Personal mythology

Everything I find written about practicing homosexuals intimates that they were aware of their "difference" from an early age, and certainly from their teens. But in my own experience, the two homosexual men I knew best only turned to their own sex in their mid-twenties, after considerable experience with women. And I would like to be sure that this business of young teens being already gay is not a matter of retrojection and personal mythology. After all, there has hardly ever been a teen-ager who did not feel "different".
