Hey Teen,
Yeah, have had gyne since about 13 or so. 37 now and just had surgery. Results look good so far. Mine's not a bad case as I always kept in good shape otherwise and covered it up a bit with some body building - seems that a lot of gyne guys are into weights.
My comments about it not going away are from research. I, too, once was your age and hoped and prayed it went away. So, I don't want you to feel that I lack empathy for your situation... I feel for you brother. Been there. I think if someone had told me that it wouldn't go away at 16, i could have coped better, rather than hold false hope.
I can tell you, that there is a lot you can do wihout surgery. You can keep yourself in great shape - a fit guy with puffies looks a whole lot better than a fat guy! If you hit the gym, work yoru chest with bench press and particularly the upper chest with incline presses - this hide the puffy nips under your clothes because your upper chest extends further out than your nipples. As well, choose clothes that are more flattering - looser and horizontal stripes or lettering works well.
I coped pretty well. At about age 16, I adapted and did those things and never really let it get in the way of anything from girls to sports to going to the beach. Mind you, I wasn't really keen on the beach, but at least I didn't miss out and I am glad I didn't looking back. It gets easier to cope with as you get older. It just becomes less of an issue. It's also not an issue for girls really (unless it is an extreme case I suppose), so don't worry about that either. They are waaay more worried about what their boobs look like!
If I were you, if you are thinking about surgery at all, wait until 18-20 so you develop closer to your full proportions to see how you look. It may not stand out as much once you fill out. If you are not happy then... then consider it. I think it's better to get the surgery at 20 than at 37 as your body is more resilient and the result will be better.
So, there is some hope that it will look better in the next few years, but I can pretty much guarantee it will be there to some degree. You just have to make the best of with what you have (don't wait for them to magically disappear). I know what you are hoping (from experience). Good luck young fella.
