Years back I invented a new type of vulva piercing that I called "Princess Dianas." Since I developed the placement and coined the term initially, I determined that they are called "Dukes" when they're on a transman/FTM.
I specialize exclusively in nipples and genitals, and I am extremely happy to pierce you whether you identify as gender queer, non-gender-binary (NB), trans, intersex, other, pre-op, post-op, non-op, you're on hormone treatment, or not, etc. The bulk of my experience relates to female-to-male (FTM) anatomy, but I have also pierced male-to-female transsexuals (or transgender, if you prefer) and other NB clients.
Whatever your identity and morphology, I'm happy to use your preferred pronouns and anatomical terms. I feel fully confident I can perform piercings that suit you and your individual build. I'm perfectly comfortable with any variation, and fairly culturally competent in this realm.
If you are taking hormones, I do suggest waiting to be pierced (in these areas) until after you've been on HRT for two years, or maybe even longer, for the bulk of the tissue changes to take place. You may also wish to consult your doctor for his/her/their opinion.
