Let's start with my ears— specifically that I got them pierced last weekend! That's something I've been meaning to do for ages and only just now finally got around to, and I'm very happy with how they look. :)
The actual piercing didn't really hurt much, but at the end of day, once I'd kind of forgotten about the new bits of metal in my head, I carelessly took my shirt off and was like OHGODWHY...
I guess pierced ears aren't really a gender thing per se: lots of boys have them and lots of girls don't, and even before I began questioning my gender I'd considered getting it done. But they do give me the option of sticking feminine jewelry in there, which is just one more cue I can use to help people read my gender correctly, so that's nice.
On an unrelated note, I just finished reading Nevada by Imogen Binnie and I absolutely loved it. Like seriously, if you want to read a novel with realistic, complicated trans characters, you should check this book out.
