Nipple Piercings

I had my nipples re-pierced about 2 & 1/2 months ago. I used to have really sensitive nips, but after I took the first ones out, I lost sensitivity. I remember the second time being okay but not overly sensitive during the first few weeks. The last time I got them done, I remember the sensitivity being very intense (but not always a bad thing). This time, I had a few issues that I’ve never come across with my previous ones. For the 24 hours, one of them wouldn’t stop bleeding. And it was a lot! The other was absolutely fine. Then within the first week, that intense sensitivity was back! I’d say for a good month after that, I had zero issues. Sensitivity went away, no crusties, blood or discharge. I’m now experiencing a lot of crust (which in fairness has reduced since having the bars downstairs-sized). There is very minimal blood. Not much to write home about at all. But I can get a bit of white/ very light yellow discharge from both of them. Is this a normal thing?

I was wondering if because I’ve had them done before, this could be affecting the healing? And how long do they normally take to heal if you’ve had them previously done? I’ve heard that as a male, they usually heal quicker??
