So, since I can remember, I had two, one under each breast … One I did have removed bc when I was nursing my daughter (my 2nd child I nursed), it started to grow and that made me concerned … So, under one breast, I have a scar (looks like I had stitches) … Then, the remaining extra nipple, it’s tiny … no sensation, nothing … as sexy as any other mole, but it’s definitely a nipple. Now, my oldest son has an extra nipple, but it appeared a in his teenage years … Also, nobody can tell, he goes shirtless, it’s a non-issue. When I was in college and would drink, I loved showing the extra nipples off 😂 Like a party trick!
