Ideally you should wait until your nipples are fully healed before doing any type of nipple play. It is important to wait through the entirety of the healing process because until 9-12 months your body has not finished developing fistulas. This means that you have a higher risk for ripping or tearing the piercing.
Keeping this in consideration, can you swim in the ocean after nipple piercing?
since nipple piercings are more prone to infection than other piercings. H2Ocean is steralized salt water cleanser, just for piercings! The ocean is not! If you had it professionally done, then your piercer should have told you to avoid excessive exposure to water for six weeks.
Likewise, does it hurt to wear a bra after getting nipples pierced?
