Piercings!

Do nipple piercings hurt? Anyone have them done? Did you lose feeling or did it make you more sensitive? I been thinking of getting mine done for like 2 years but haven't! Lol I think about going then I'm like no not doing it voice in my head stops me lol. But I have a high tolerance for pain though so I don't know why I'm scared. I have my tragus, ear lobes, cartilage, lip & nose pierced & have 5 tattoos! Guess I just want to get some opinions. Thanks ladies!!
