Tongue piercing suggestions..

So Iv had my belly button done, nose, 2 holes in my ear lobe, my cartilage done, and my industrial bar done. My piercer told me that if I can heal my industrial bar then I can heal anything on my body because she said that’s the worst piercing to heal. I got that one done a couple months ago and so far it looks really good. I want to get my tongue done but I’m not sure about the pain and pros and cons to it. What do y’all think? & I have a small tattoo of a penguin on my shoulder. You’re probably thinking why a penguin.. my and my mom have matching tattoos.
