Quotes from Piercing FAQ
MALE NIPPLE PIERCINGS
Because most men have very small or flat nipples the piercing is usually made behind the actual nipple and through the areola so that the piercing is approximately 3/8» to 7/16» wide. Nipples which are well defined and larger than ¼» wide can be safely pierced through the base of the nipple.
Piercings made through flat areas, like the areola, are more likely to migrate or reject. If the nipple is completely flat and cannot be easily pinched the tension of the skin creates presure which may cause the piercing to migrate forwards. Often, the nipple is more easily pinched vertically, in which case a vertical piercing is more likely to be successful. In some cases, the nipple is more easily pinched at a diagonal, or perpendicular to the long axis of the nipple if one is present.
Initial jewelry: Captive bead rings, bead rings, circular barbells in 14 to 10 gauge, ½» inside diameter or larger. The inside diameter of the ring should be approximately ¼» wider than the length of the piercing.
