Since I was a kid I always felt that way.
I liked some kinds of boy stuff, like playing with toy trains, building stuff, mild sports, but not heavy into it. Loved nature but hate hunting & fishing. But I also liked girly things, aside from just their outfits that were way cooler than most boys clothes of the era. Emotionally I was softer, kinder, gentler, & quieter than most boys. Male teachers hated me as a little wimp, where the woman teachers loved me as a sweet good boy.
I hated sports, but didn't mind playing them with close friends from the neighborhood. With friends, it was just fun with neighborhood kids rather than fierce, forced macho competition like promoted in the schools. In the neighborhood the boys & girls played together, where at school, boys & girls were separated for different activities & sports.
Even as late as 1970, girls were still prohibited from wearing shorts, or pants to school. They had to wear dresses only... even in below zero F weather. In the neighborhood, the boys & girls pretty much wore almost the same thing... jeans, shorts, & a t-shirt or ordinary shirt.
What was macho or fem was more blurred in my family too. Mom & dad both did the cooking, cut the hair in the family, painted & remodeled the house, & did the same chores. But dad would be the one to climb on the roof, or under the house to fix stuff, & fix the cars, while mom fixed all the family's TVs, & did the house wiring.
Dad was a crane mechanic at the steel plant, when mom didn't have to take care of 6 kids (5 boys & a girl) she was a TV repair person, & later a secretary for a female politician in the days when it was rare for females to hold an elected public office.
To blur things further, as soon as we were able to walk we were expected to help in the chores. There was no such thing as woman's work or men's work. The boys & girls would sew on a button, mend a hole in a sock, cook, do the dishes, mow the lawn, shovel snow, & clean the house. Indeed, the kids were responsible for all the dishes, & house cleaning. I never saw my mom or dad do dishes, dust, clean house, or run the vacuum.
Except for my sister's kindergarten graduation, & her communion. There were no pretty dresses in the house. Just a few very plain ones. I only saw pretty girls clothes on TV, in school, & in church. Being raised around 5 brothers my sister didn't care about dresses, & not much about girls toys/dolls either. Although we all loved the easy-bake oven. Indeed, she enjoyed sports more than I did.
I had no clear example at home of what a boy or girl should be like at the time. My older brothers were always out & about somewhere, so I spent most of my childhood years with my mom, sis, & dad when he wasn't at work.
So we grew up not knowing much difference between what it is to be male or female beyond the physical differences, & was out of place in the real world of the 1960s.
