Now there is breast enhancement surgery, I don't know what men think. 17 years old is ok, it will protrude in the future. Don't worry, psychology is very important. As you said, this situation varies from person to person. Maybe she took hormones, that is, she ate too much fast food, but it was harmful to her health. You should let your breasts continue to grow, and then look at your breasts around the age of 25. I don't see any tricks now. Everything is a wild guess. Don't be shy, don't feel inferior. At this time, you have not stepped into the society, and it is useless to feel inferior. Let's summon up courage to move forward!
