The main misconception that stopped my egg cracking was that trans people "always knew" they had the wrong body, whereas I, clearly male (look, I've got a dick and everything) merely wanted really badly to be a girl. Totally different, ah well.
Also I was really strongly opposed to cosmetic stuff: surgeries, tattoos, piercings etc. Like, easily deal-breaker level. I always thought it was kind of a weird hangup and I should talk to someone about it, but I'd get panic attacks whenever I thought too hard about it so kind of let it be. Turns out the reason I was so obsessed with body modification was because I wanted to change mine and I was jealous of anyone else who could.
And just the general misogyny that comes from growing up in an almost exclusively male environment.
