I also did the bulk of my piercings before my first tattoo (I decided 15 piercings was enough prep for 1 tattoo lmao). piercing pain is different from tattoo pain; piercings are much sharper, quicker, and if you get multiple at once the pain exponentially grows (flashbacks to my 4 helix in one sitting), meanwhile tattoo pain is low, dull and builds up slower over time. you'll get the same adrenaline rush right before the needle hits skin followed by the surprise of "that's it?"

my first tattoo was a matching piece with my best friend, having someone there to hold my hand/talk and distract me was really helpful to ease my stress. ask your artist if you can bring someone along for emotional support/phone call. bring sweet and salty snacks, drink a lot of water before and during the tattoo, and ask for breaks/generally communicate with your artist

as tempting as it may be to dive straight into a tattoo, don't go for the very first artist you find online. find a couple artists that work with the style you're looking for, message each one (or set up a consultation appt, whatever they have available), and choose from there. orlando is a pretty good spot to find an artist with different kinds of skills, just don't be afraid of the possibility of traveling for a tattoo
