Even though he was a man, his chest was slightly smaller than that of woman B. It doesn't hinder my life, but I am very reluctant to wear t-shirts in the summer and my shoulders tend to slouch for no reason. Meanwhile, his junior had gynecomastia surgery and was very satisfied, so he performed gynecomastia surgery at Dam Soyou Hospital in Gangnam. Compared to other hospitals , I was worried because I was told that they would perform a suitable surgery to remove mammary gland tissue from the breast as per the purpose of the surgery, rather than for cosmetic purposes or to shape the breasts. Reviews say that other hospitals do a good job of shaping the breasts. However, I seemed to have confidence in the surgery, so I went ahead with it, and it has been over 6 months since the surgery, with no side effects and I am very satisfied. I am very satisfied that I now know what a flat male chest is like.
