Hi Alone,
I once was 19 (50 years ago) and surgery didn't exist for this with D or DD breasts, or any size, by that time. The guys who harassed me made my life hell. On the other hand, I never had trouble with the girls. They were completely used to the idea of breasts and I even got offers of the "you can feel mine if I can feel yours".
Knowing my almost lifelong health history now it is just as well I couldn't have tried surgery. I found out the hard way later on that every injury, whether surgical or illness or physical trauma was that I did not heal well or quickly (not even normally) because of my genetic polymorphisms. So now at 69,most all injuries and surgeries and so on are all miserable pain. With some proper corrective nutrition, about 90% of the pain has relieved, the 10% left is barely under control with opioids.
I belong to a nudist club and I get lots of good hugs from the ladies. After school I had no problems with harassment. Even during school it is a few people, a handful at most, who harassed me, they just had big mouths. I certainly wasn't going to hate myself or body for something 50% to 70% of men have.
Do what will make you happy. Perhaps 10% having breast surgery regret ever getting it, even if "completely successful" because the scars show that they had breasts that were surgically modified. They are not freed from their self imposed prision by surgery. Then there are the normal risks of surgery. My father was almost killed by a minor elective surgery. I had a friend who was put under anesthesia and died on the spot before the surgery even started. Good luck.
