This subject is so funny to me!
My poor mother despaired of my preferences for baseball and toy guns. She kept buying dolls for me but I kept stripping them naked and dragging them through mud.
It wasn’t until my mother lay dying she confessed to being afraid I was a lesbian when a child. Of course her fears were unfounded. Sometimes a little girl is a tomboy without any sexual context involved.
Curious how it is socially acceptable for a girl to be a tomboy but not the other way around. In fact, there is no real antonym for "tomboy" other than "sissy", which is about the worst thing in the world you can say about a boy.
Growing up, the girls often joined us in "boy" games such as stickball, shooting stuff with BB guns and catching frogs. But if a boy ever did anything with the girls such as play house with tea sets and Easy-Bake ovens, he would be ostracized.
