There may be a few similarities between different people's individual
developments but it will be more likely that your's will differ from anyone elses.
When I first started taking hormones and androgen blockers, my nipples swelled
and became sore within a week, a know-it-all "Old School ->-bleeped-<-" b----h had the nerve to tell me,
"That's impossible" as well as try to tell me that I didn't know what size pants, skirts and shoes I wore.
So as always, as with every other aspect of your transition, "Your mileage may vary"
