Plenty
*From a young age, I despised "girl" culture, I remember seeing high school musical, Hillary duff, backstreet boys and teen mags that were typical girl things to fawn over and I despised them so much I found girly girls to be inferior. I've since improved my attitude on "girly girls" knowing I don't have to be and an not one of them.
*When I was a kid, my brother would always pose to all his friends that I was a "scary" older sister and I could kick their asses. There was this kid on my street who took me up on that offer and we had a wrestling/grappling match on the trampoline in my backyard
* When I tried to play with my brother and another boy, the other boy pushed me away because I was a girl and he didn't want me to play with them. That made me so upset I cried.
* To me when I eventually earned the title "tomboy" by my confused mother seeing I never wanted to act like a girl, to me it fit because it was a way for me to be myself which meant I didn't have to be a girl like the girls, I was something else
*My mother asked me a real serious question one night before bed, about how I refused to play with dolls like bratz. I was pretty oblivious, and honestly I didn't have a real answer, I just didn't like them, they didn't appeal to me and I was completely indifferent. She didn't accept the "I just don't like them" answer so I gave a really dumb response like "they have big, weird lips" for her to accept it. Looking back, seems like a loaded question about my lack of femininity.
*When I first hit puberty and began to develop buds, I was caught completely off guard, and when I looked in the mirror I remember an overwhelming sense of misery that my life would change forever, but I had to accept it and move on. I eventually settled on accepting it with indifference, but I got used to it. My period was similar, on the one hand I hoped I would never get it but at the same time the longer I went without it I started to really worry that doctors would have to perform invasive tests on me and look down there to find out what's wrong (I must've been 13-14 when it finally happened). It was followed by immediate regret because they suck and it's not something I really wanted and I only wanted to be "normal"
*When I was a kid I hated the idea of growing up to be a "woman". Girl was okay and all, but being a woman would suck, I never wanted to think about getting older. I also never wanted to get married, the idea of it was infuriating. When I was very young I didn't want a boyfriend either, that part has changed but to this day I don't want to be impregnated and have biological children, I just didn't want to grow up and have children as a kid. Regarding dating, I never considered myself to be someone to have the submissive girl role, where guys open doors for you and buy you flowers and jewelery and pick you up bridal style. I pictured my relationship on equal terms where we both care for each other and switch being submissive, I didn't want to be fawned over like a girl and always had a protective/caring role to a partner in addition to being submissive.
*I was a loner in school, I didn't like playing with girls and boys wouldn't play with me, so instead I read books. I had a complete lack of social life. Occassionally I made a few girl friends because I couldn't have any real guy friends, so by high school when I did make Some new friends for once in my life it was the first time I had real guy friends in a mixed group of friends, and it was very fulfilling to be able to hang out with them.
*In middle school when puberty hit I distanced myself from being all lovey-dovey to my younger brother and my family. I was basically a stereotypical teenage boy who did not want to hug his own family and parents, and at school I propagated the whole sibling rivalry thing towards my younger brother. I was very standoffish and did not like affectionate contact from family. My mom described my attitude later on as Axl from the TV show "the middle"
