You do have a very mild case but if you don't have gynecomastia, then i don't know what gynecomastia is. You obviously are not obese but your nips are protruding from gland.
Here's the problem: I would guess that if you have surgery that you will maybe have a 50% improvement. It looks like mine before surgery. I have improvement but I would like more. I still haven't had my one month post op so i'm not sure if there is still swelling.
Luckily, you look better than most people after gyne surgery. Some people have like A, B, or C cup breasts and they are usually happier with the surgery than those with just puffy nips.
Keep hittin' the weights and find a surgeon that will prime you for realistic results and make a decision from there.
Just my opinion.
Good luck
Peace
