I'm 21 and got my ears pierced for the first time last week because i used to be scared of needles but i'm actually okay with them now! I got four piercings in one sitting, a first lobe and a second lobe on both ears. I got them done at a proper piercing place with good reviews (and needle not gun) and it didn't hurt much at all (and i have a low pain tolerance). The fourth one hurt more than the first one though, i wouldn't have wanted any more done in that time period. I don't know how to describe it, it was just a bit of a sting i suppose and then it was over, the piercer i had did them really quickly.
I haven't had any issues so far, i've been bathing them in salt water twice a day and i never touch them, sometimes i accidentally brush them but i generally don't want my hands near them haha. I can't wait to be able to change them, i think i'm going to leave them 8 weeks just to be sure they are healed (i don't mind the ones i have in now though, they are really pretty).
I would love a helix in the future, or even a daith, but the fact they are through cartilage puts me off haha, they look so nice though.
