You should discuss this with your parents, since they will be the ones taking care of you and paying for your medical expenses should any complications arise. Plus, it's just a good idea to be transparent with your parents to avoid arguments and conflicts.
There are inherent dangers with any do-it-yourself procedure that involves piercing your skin. You mentioned one, and this lists several others: https://www.vice.com/en_us/article/qvdq3b/how-safe-are-stick-and-poke-tattoos
Wassup! I have given myself a few stick and pokes,basically before you do it (i know I can't stop you if you have your mind set) know it's stabbing yourself, over and over and over until it turns into a shape, sometimes if you don't do it deep enough you just feel pain, you might bleed, but you don't get the tattoo (Its just a bunch of dots!!) And you have to take care of it, as a teen who used to self harm I can say stick and pokes are pretty similar, so, just, keep that in mind, and im all for you do you boo decorate yourself however you want, but I would wait for a professional, i wish I did tbh
Just print a piece of paper and use it. Laser treatment is expensive and can hurt. Just the same old way, but you won't have any regrets in the future.
