A number of us have posted, as 1974cookie did above, about our so called 'tomboy' ways as children. I was an avid reader of anything at all but especially the Famous Five, Secret 7 books and of course, Little Women. I never identified with the 'girly' characters and between about 6 and 9 would probably have chosen to be a boy. Boys had more comfortable clothes for tree climbing, bike riding, fishing in the local pond and many more exciting games. The tv, books and fairy stories were full of tales of daring do and rescue, always with boys at the centre. Girls were usually to be found whimpering in a corner. No wonder so many of us identified with George (famous 5) or Jo rather than Beth in Little Women.
I'm not minimising the difficulties adults and adolescents experience around gender and sexuality As I said earlier, I don't support giving meds to pre pubescent children in order to suppress sexual development.
