I don't "feel" like a pervert, I was just pointing out that the common thread of cisgenderism (the way I see it, if cis people can call "transgenderism" an ideology that holds that transgenders are people, I can call "cisgenderism" an ideology that holds that transgenders are
not people [and before you complain, yes, I am exaggerating to get my point across]) is that if a trans person's backstory does not reinforce gender roles, then they must be some kind of pervert. See: autogynephilia theory.
As for what makes my experiences of gender dysphoria different than BDD, I'll explain: the aforementioned "consequences" of my primary sex characteristics (i.e. male puberty and testosterone exposure).
That's what made me "feel" like I'm a woman. That, and the fact that estrogen, while not a panacea, helped my mental health quite a bit. Though yeah, I will concede that the fact that getting rid of one's genitals is less physically debilitating than getting rid of one's legs or eyes (what you call "aesthetic") doesn't hurt.
Hopefully this made sense and wasn't just a bunch of deranged rambling. I feel like it was the latter, but...
