@roadriverrail Hips: That they don't grow the way my boobs seem to. I just want hips (and my ass) to pop out, but I'll probably never have them.
I didn't want boob changes at all and researched binders, hiding clothing, and actually filled out insurance pre-authorization for mastectomy just in case they started growing. 100% against having boobs. Actually put off starting HRT for a bit because of that. But the mental changes were so necessary I finally started.
Then at about 3-4 months, something shifted in my brain and I was like "Oh these started growing, and I never ever want them to stop. In fact, I want them to be enormous." Not sure if the E removed a block or actually changed my relationship with my body, but yeah, total shift.
