cc

Hi so I got my nipple pierced back in May and I’ve been having some problems with the right one first the bar was way to short and I had them switch it to a longer one and made sure they were titanium it looked way worse then this prior I still get crusties which ik is normal however today it’s just been really painful I’m also just getting off my period but I just want to be sure! Thank you in advance
