as long as you don't try to pierce the nipples

Yes he did. They were pierced earlier but closed so he had it done again.
If you're a woman you probably won't be able to breast feed.
Try making a list of pros and cons and ask yourself why you want to do so.
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 all depends on your anatomy. Your piercer will pick the size that fits you best :)
Pancake nipples is a term used for people who have nipples larger than 10inches in diameter.

Don't be overly concerned about it. Some people have inverted nipples. Do not worry about it!
