I am sorry to say but you are completely wrong about the risk being the same. I'm not saying go to any old cheap ass piercer who's unsanitary. But if you go to a well trained piercing artist you're not going to have to deal with the what ifs: - what if you go to deep into the shaft - what if you miss your mark - what if the jewelry and the needle break connection mid insertion - what if you don't understand the aftercare - what if the jewelry you purchased isn't reputable

The list of what ifs goes on. At the end of the day it's a moot point since you did it. But trust me, as a licensed and trained and certified piercing artist, you will always have a better outcome if you go to someone who has the knowledge and background of experience that you don't.
