It varies from person to person, depending on the size of your nipple.
How long has it been pierced
You can get it done again once you're sure the piercing is healed inside as well as out.
It is best to wait about 6-8 weeks like you would with any other piercing :)
As long as you are taking care of it nothing would happen and it should be fine.
6~8 weeks and even longer depending on how the piercing was done. As long as the mater is whitish yellow you are o.k. and that is normal discharge, it will ease up as the piercing heals and becomes seasoned.
Provided it was done properly and it is deep enough, it shouldn't reject and should last for as long as you want it.
Yes, as long as the gauge is correct for the tongue piercing - for example : nipple bar is 14 gauge - usual tongue piercing jewellery is 14 gauge and the length of the nipple bar is the correct length for the wearers tongue (this varies from person to person). Basically - if it fits - wear it!
when i went to get mine done they said to wait 2 months, but i think that's an average i havent had my done more then a month and i think its ready to change
Yes I have had lots of clients who have received nipple piercings and have successfully breast fed there children. As long as the piercings were done correctly and healed without issue breast feeding with the jewellery in or out is not and issue.
It varies person to person. On average, it takes 3-6months for the piercings to heal completely. Everyone is different.
2-3 months before the piercing can be submerged. You can go swimming now as long as the piercing doesnt get wet.
