One or two nipple piercings?

I suggest you pierce one. Wait see how it feels and if your planning to wear a bra. If after a day or three it feels fine then go for both. Thats kinda hot pierced nipples😈

I think nipples are just fine without them

None

what a waste of perfectly designed nipples

Zero

I say if you are going to get your nipples pierced you might as well go and get both of them pierced because if not then it would look very loop-sided. I would suggest getting both.

Two for symmetry.

ouch? or ouch ouch? you decide.

None.

two, sexay! ;)

One tbh encase you want to take it out. But two would look better under a shirt.

I think, nipple piercings are disgusting - but hey, it's your body.
