Curious of Nipples piercings

Hi ladies, I’m just curious on how bad it feels when you get your nipples pierced? I have a total of 7 piercings right now; both my ears twice, my nose, my tongue, and my eyebrow. I have always wanted my nipples pierced. I am suppose to be going on the day before my birthday, so Thursday. And I’m trying to figure out how bad it might hurt I seem to have an extremely high pain tolerance. I didn’t even flinch when they pierced my tongue. So I’m just curious!
