Does it affect/improve sensitivity? Personal experience says no, but for many women, whose piercings have healed nicely, their nipple sensitivity increased dramatically.
Also know, do your nipples grow back after piercing?
Smaller injuries can heal with proper care. However, if a nipple is completely damaged or removed from the body, it won’t grow back. While rare, one or both nipples can be lost in an accident.
In this way, how bad does it hurt to have your nipples pierced?
The jolt of pain felt from the act of puncturing the nipple only lasts a second or two. According to people who’ve had it done, it feels like a quick bite or pinch. Beyond that, you can expect your nipples to be pretty tender for the first two or three days.
