How can people be so sure that they feel like a girl when it is impossible to even know how a girl feels unless you are one?
Does this mean that when boys think they feel like girls they just relate to the generalizations our culture places on females?
How can you be certain that all girls feel similar enough such that you can generalize what it feels like to be a girl when you can't even truly know what it feels like to be any person other than yourself?
Truth be told, I had a very hard time getting my head around this myself. I had the same doubt even after I came out. Like, how can I claim to 'feel like a girl' its not like I can access the minds of women or something for a comparison, all I have is my own mind.
But at the same time, I definitely felt "better" when I was seen as a woman, and hated the masculine aspects of my body, which early on was enough for me to come out and pursue transitioning. I only got a good handle on this maybe a year after.
I say the folly of this question is the assumption that gender is just an abstract thing which men and women do in our society. Like that if you like dresses you're a woman, and idk, cars or something, you're man. But neither of these things are inherently gendered, I mean like dresses are just cloth tubes you wear and car didn't exist 150 years go.
Bizarrely, I really think it comes down to the body. Like maybe I could be a man if I liked makeup, dresses, purfume, ect. Maybe some hypothetical guy (cross dressers?) might still be comfortable saying they are a man with all that. But how can I be a man if I desire to have breasts, a vagina, hate my body and facial hair, hate my height, ect? If someone hates their fundamental male biology, how can they be a man?
Now I know what some reading this might be thinking "well maybe they aren't their assigned gender, but that doesn't make them the other gender." I could be a not-man but still not be a woman. For this it comes down to how I want to be seen I guess, I mean I guess I could go around being referred to as gender neutral if I needed to, but I would be / am so much happier if I am seen as a woman. I will admit however that this distinction is far more fuzzier. Again though, the whole desire to have breasts is a pretty big clue as to what I am.

Don't assume that us trans people haven't thought about this, we are our own biggest critics sometimes. :P
