I got my ears pierced 15 years before realizing I was transgender, lol, at the age of 18. Of course I also pierced my tongue (twice), and I had an "Industrial" piercing in my right ear. I took the Industrial out in exchange for my dad buying me a car, and the tongue piercings because, well, they sucked...
Hindsight being what it is, I got piercings and got into the goth lifestyle so I could present more feminine/andro, and then eventually supressed it all for another 13 years or so now...
My earrings were a symbol back then, and never closed up even after years of nothing in them. I see the next set of piercings as being affirming though, another set or two of holes in my lobes for sure, maybe a ring in my cartilage, hehe. All gender affirming.
Boobs though, that's something I can't remedy overnight and is evidence of the long road ahead of me of becoming a woman on the outside to match how I feel on the inside. Until that day comes, I won't be getting anymore ear piercings though. I'll just keep the two holes I've already (still) got.
