I have 9 piercings: 2g lobes, 2 helix in left ear, industrial in right, tongue, and nipples.
I have 2 tattoos: my name in Hebrew on my lower left back, and the alchemic symbol for the philosopher's stone on my left wrist.
All are post-transition. I never cared enough about my body pre-transition to decorated it.
I slowly add to my collection. I tend to wait about a year after I decide I want a body mod before getting it done, so that I'm sure.
