I suffer from this too. I am in pretty good shape but I do have some fat on both sides of my chest, especially the right hand side, that will not respond to diet and excersize and has been there since I was a little kid. It is called gynecomastia and about 15% of men of healthy bodyweight have this problem, so you are not alone. You are only 14, so I would suggest waiting it out until you are at least 20, but if it still is a problem, surgery is an option. It is a fairly simple outpatient procedure practiced by most plastic surgeons, and it is similar to a small scale female breast reduction.
