Yo, I am 17 years old I've been lifting for 7 months now. Recently I've started thinking if I am starting to get some gyno on my nipples. They're somewhat sensitive and I can feel some sort of lump underneath them. I used to have same sensitive feeling on my nipples few years back also, but it disappeared.
While I realize puberty is a big factor, I'd like to hear your opinions if this situation usually goes away or anything that's related to topic. Just to clarify, I am not taking drugs, and not really fat either.
