Sadly, a lot of kids end up getting gyno when their test kicks in. This is naturally occuring. If there are no lumps, it may be "psydo gyno". I see a lot of times, guys who have this are genetically more "chesty". It often runs in the family.I had this. I got lypo to suck the fat cells out and it made me feel a lot better about myself. Interestingly, now that I have less fat cells in my pecs, they get diced up quickly when I diet. 12 wks out from a show and I have striations! haha. The good news is this is just fat, so as you diet down, this will improve. It's probably going to be a resistant area to fat loss, meaning that as you diet down and get leaner, this area won't show changes until you have gotten a good % of the fat off. Some guys need to get to lower single digits and it still is a problem, in their minds. 

Trust me, I know how it feels. I got fat at about age 14 and with that came the man boobs. I remember feeling sensitivity at the nipple but I didn't understand why and no one around me knew what was going on. I felt shame and stopped taking off my shirt in the summer. In some ways, this was a reason I got started with BB to begin with. At this point, no one would ever guess it was once a problem for me. I'd suggest that you first try to diet down and see how things shape up. If you still are unhappy, then consider spending some money with a plastic surgeon. Also, be careful with steroids that convert to estrogen. You will probably be more prone to estrogen issues
