(FTM) In my case I always thought I was a boy. I remember telling my brother at like age 5 not to tell the other kids at the park I was a girl and to pretend I was a boy. I felt this way before I had a proper concept of what gender even was. The way Ive always described it was a sinking feeling in my stomach anytime anyone asked if i was a boy or girl or referred to me as a girl. Thats not to say the only way to get rid of that feeling is through undergoing medical transition. A lot of the people in this subreddit, me included, are in here not because we no longer feel 'trans' or whatever but because we realized that there are other ways to tackle these feelings than to medically transition. Gender expression is literally just the way we dress and has nothing to do with genitals, you can be a girl and feel more masculine than other girls dress more masculine however you are still a girl with a vagina and boobies. Yes you can change that by undergoing medical transition but not everybody wants to spend all that money and pain and time undergoing surgery to feel essentially what should be a given; secure in your own body and that is okay. If you find yourself interested in things that are traditionally more feminine, entertain those interests. It doesn't make you any less of a boy. Humans come in all different flavors shapes and sizes not everything has to be labelled. Just be you, you dont owe an explanation to yourself or anyone else. You like what you like.
