First, I'm going to say that I have not read anyone else's responses to your original post, so I have no idea as to what others have said.
Second, in many ways, I can relate.
I too am relatively comfortable in my own skin, but I have to admit that I still wish I was born male. My dysphoria is relatively mild in comparison to many others. I don't mind my breasts, its only been the last few months that I'm kind of like "they're in the way, why must I wear this stupid binder? I want to go topless like other guys!" I don't hate them, they're merely annoying.
As a child I remember being angry at my Mom for being born the wrong gender. Its one of my earliest memories. So I did the typical thing, I "out-boy-ed the boys." I was the fastest kid on the block, was the best at kickball and baseball and was the fastest on bikes and on foot when we raced.
However, since the end of puberty, I've never really been depressed about being born the wrong gender, its always been more along the lines of "I'm the wrong gender, what can I do about it now?" So for years, I was androgynous in my clothing choices, opting for jeans, t-shirts and tennis shoes for the most part. I've always walked like a guy, and some of my mannerisms could be seen as male. My family has always referred to me as a "tomboy," they were half right. My Mom would almost always have to beg for me to wear a dress at important family events. The last time I did was at my younger brother's wedding, over six years ago.
But then again, I didn't know that I could physically transition until a little over three years ago. I knew that there were MTFs, but it never occurred to me to look into FTM transitioning. I accepted this body and simply hoped that in the next incarnation I would be born male.
I suppose I was lucky in my choice of career. Being a Paramedic for many years gave me broad shoulders, strong arms and legs, and a broad chest. "Carrying people for a living" does that to you.
So now that my kid is grown, and I am no longer in the work force, I'm transitioning in to the man I should have been. I've always been happy for the most part, and now that my body's slowly evolving, I'm finally starting to feel truly happy about my physical self.
I don't really care too much that I have hips, my breasts are merely annoying and prevents me from going topless, and my groin, well, lets say what's going on down there is interesting. Sure, I'd love to be able to do many of the sexual things that a cis man can do with his groin in order to please my partner, but I make do.
So I suppose what I'm saying is that, "not everyone has soulcrushing, crippling dysphoria about their gender, some of us merely change what we can when given the opportunity."
