"All good things come in threes" definitely ranks true when we talk about piercings. We are all falling for triple piercings!
They're associated with 90's rock and club-culture and often considered one of the 'sexier' piercings: tongue piercings are like any other piercing, the only difference is that they are placed in your mouth.
Whether you’re speaking, swallowing or chewing, you’re always using your tongue. It is used continuously so you want it to be as comfortable as possible.
