if it went wrong 你 could seriously injure yourself because the belly button is dangerously close to several organs and blood vessels, its definitely unwise, though im one to talk, cuz i want to get my eyebrow pierced, though fully aware that the eyebrows are close to a major facial nerve.
Well they hurt depending on the ink, how well your skin takes it, etc. But I think a piercing would look really good on a flat stomach. If 你 already have a flat stomach, people will become even 更多 attracted to 你 with a piercing there. Just make sure it doesn't get infected 或者 it will become crusty and disgusting.
The decision is entirely yours. I have a lot of piercings all over my body. Body modification in the form of piercings and 纹身 are a hobby for me, and every time i get a new one i feel better. If 你 want to get your navel pierced, then do it. But i caution 你 to keep it clean as infection is rife. And as it's near the centre of your body, any infection can go either way and cause major damage to organs, skin cells blood vessels etc. Also, make sure you're not allergic to anything the artist will be using, any metals the piercings will be made of, any latex gloves, liquids, medicated sprays etc. And if the slightest thing goes wrong, 你 go straight to the hospital but DO NOT take it out! Taking out infected piercings, especially those in the naval/genital areas could cause 更多 damage then good. Leave it to medical practitioners to take it out. But through all the bad things that can happen with any piercing/tattoo 或者 body modification at all these are very rare (make sure the artist is fully certified/qualified first). I have my naval pierced, and i have had no problems with mine :) As have my friends. The choice is yours.
