According to several different doctors seen over the years I do not have gynecomastia, but do have natural 40 B's. Have had them for many years. Got a lot of teasing over the years, even when I was in the Navy. But since I have been a CD since age 6 or 7, I did not, and do not now, mind. I love my breasts!! I wear a bra most of the time, unless I am going to be around my family, or friends who like to hug!
