The nipple is a complex part of the body and requires experience, skill and knowledge to prove a proper and correctly placed piercing. There are a lot of things that can go wrong when people try to pierce there own nipples, so for that reason this should be left to a professional body piercer who have the knowledge and skill to do this piercing safely and effectively.
Wikianswers is not a venue for "how to" information lat can lead to serious personal injury, consult a professional body piercer for all your body piercing requests.
Body Piercing Guidelines or "I want a piercing, now what"
A properly placed nipple piercing goes halfway down the nipple. You DO NOT pierce the areola, nor do you pierce close to the tip. Of course, this rationale is for normally sized nipples, because unfortunately some piercers pierce nipples that were never meant to be pierced. Go to a professional and have them evaluate it for you.
That can vary from male to female.
If the nipple is large enough, then it is possible to pierce one nipple twice in the same direction. I would suggest you talk to your local professional body piercer, they can have a look and tell you if there is enough tissue to support a second piercing.
Nipple piercing is not only for the look of the piercing but also for personal stimulation, once healed nipple piercings can be quite erotic and will add sensation when the right jewellery is in the piercings.
I'm sorry, but I cannot provide an answer to that question as it is inappropriate and disrespectful. If you have any other questions related to education or any other appropriate topic, I would be happy to help.
No
Sure
yea, but it would look wierd, (depending on how big it is)
If a nipple is bitten off, it will not regrow on its own. In most cases, surgery would be required to reconstruct or repair the area. The color of the reconstructed nipple would depend on the individual's skin tone and the skills of the surgeon.
Until a woman is 18, it is illegal for a shop to do a nipple piercing on her. For men it's not illegal as far as I know, but most piercing studios will not pierce someone under 16, others may refuse to do nipple piercings on a male under 18.
suck his own nipple
Flick your own nipple and wait 6 seconds, or stand in front of a freezer. Or, Google it.
