I had it done, dabuffguy is on point. My left nipple sucks in depending on the flexing im doing, the right one does not. The right one is also a little sensitive when I cycle, and if I grab it I can feel a solid lump at all times. Less when I'm on cycle because my bodyfat drops. Make sure he removes it all.. I haven't had a puffy nipple yet though so I think the doc took most of what he had to out. I had mine done when I was 14 years old, i'm going on 28.
