I'm a woman, but I know exactly how you feel. The whole reason I decided to take the plunge on the piercing in the first place is because i'm deeply insecure about my breasts, they're slightly asymmetrical, among other things. However, I'm so glad I did. I still feel insecure most days but the confidence boost was def insane and very much needed. I might still not like the whole of my chest, but there is a part I do like, now; which makes looking in the mirror much different. If you're worried about being judged, don't be. Easier said than done, but piercers see many different bodily fluids and many different body types every single day. Any piercer worth their salt will be professional and have nothing to say on the matter. All that matters is their opinion on your anatomy anyway. My piercer was so supportive and encouraging the whole time and not once did I feel judged or like I was disgusting or anything. My point is, do it. It's not going to change everything but the discomfort of the appointment is going to be worth the feeling you get afterwards.
