14 ga.
A Needle.
Whenever you go in for a Monroe piercing, the piercer will take a needle, usually either a 18-16 gauge, and pierce your lip with that. It doesn't leave a big hole at all. But, if you want to gauge your Monroe, then you could have the piercer pierce with a bigger gauged needle, or just gauge it out yourself.
The smallest gauge needle that I'm aware of is 22g. But no one will pierce you with anything less than 20g, and that's usually in the nose. But, the standard size piercing needle is around 16-12g, but you can make a request to be pierced at a larger gauge, if there's sufficient flesh for it to go through.
Guns are usually 18ga or 20ga. Needles are probably 16ga but they might be 18ga.
Most piercings are pierced with a 16 gauge needle, but if you want to stretch it, I wouldn't go any larger than a 10.
It's not recommended to pierce your tongue yourself as it can lead to complications like excessive bleeding, infection, or nerve damage. It's best to go to a professional piercer who will have the proper tools and expertise to safely perform the piercing. Typically, a 14 gauge needle is used to pierce the tongue for a standard tongue piercing.
Yes, that's fine. All the professionally done cartilage piercings I have (five) were 16 gauge, and it wasn't like I had to special request that.
you can pierce your ear with a needle by burning it and put alcolhol in your ear for 5 to 10 minutes and get the burned needle and stick it in there
You answered your own question. If the jewelry is 14ga, the needle should be 14ga too. I should say though, you don't want to pierce your bellybutton yourself. Its a surface piercing and if you screw it up and it gets infected, you could be left with serious scarring and/or the infection could spread. It would be a better and safer idea to go a professional to get it done
