Im a bit ashamed, but for the sake of discussion Ill admit that I had similar thoughts around that age.
Surgery wasnt a thought and I never touched dolls but just saw myself happier as a tomboyish girl that still kissed girls. I first got the idea of girls kissing girls from some movies.
Part of the reason I didnt start following through is because I knew my parents would never allow it and my friends would not be forced to accept it.
The feeling stopped around puberty, Im 100% man and I love it.
I cant imagine the pain I would be in if my parents and peers enabled those thoughts and I went so far as to get surgery.
Hey, we all pondered the idea of girls kissing girls.
