There might be a bit of a gender divide here. It fits with what we know - after all, a lot of MTF ladies have observed that women in Western society have greater freedom of personal expression, but with that comes an expectation of personal expression. People who present as female but are quiet, shy, bland, and trying to be invisible are actually considered 'weirder' and get more of the outcast treatment than those who are extroverted, outgoing, and unapologetically individual. If that's not us (it's certainly not me), then many of the behaviours we adopt to make friends can be maladaptive, and it can actually be a relief to be free of them. But when we transition, we have to evaluate what parts of our personalities are "really" us, and what we're just doing as a performance. We've lived our whole lives doing drag and camp, after all.
For male-bodied women, it could easily run the other way - the "safe" way to pretend to be a man is to play the strong, silent, clone-of-all-your-friends type. When you transition, you might feel free to express more.
