Some of the cartilage piercings and nipple piercings hurt the most. Genital piercings aren't too bad, depending where you pierce. A tongue piercing takes about two weeks to heal, earlobes take about four to six weeks, a nose or eyebrow ring takes about three months, and a genital piercing can take two weeks to six months, depending on which part of the area you get it. Infections occur when you don't take care of a piercing properly or when skin simply has an allergic reaction to the type of jewelry being used. To be on the safe side, you should get pierced only with either 14k gold or stainless steel.
People get infections all the time.
