1. How long do they take to heal?
Depends on your nipples. It took mine about a year but my nips are thick.
2. Is it true that u can't go swimming in chlorine pools until they are fully healed?
Don't recall being told that. I swam shortly after.
3. Has anyone ever lost sensation in them after piercing?
4. Do u regret the piercing?
Nope! Will get the other one pierced one day.
5. How long until u can...have fun with them?
6. Did u wear nipple pads after they were pierced (for drainage)?
I did but not for drainage. So people couldn't see the ring.
Thanks in advance!
