The tongue piercing is not a gender specific. Usually, tongue piercing is pierced with barbell jewelry.
Tongue rings can be made of surgical stainless steel, 18kt and 14kt gold, titanium, acrylic and niobium. The most common gauge is 14 gauge. Length may differ based on the thickness of the tongue. During piercing the barbell length may be 5/8 inch to 1 inch but after it is healed the barbell size is normally 7/16 to 1/2 inch.
