At 17 I don't think you should consider surgery or be worried about it. Lots of guys at your age have slightly puffy nipples, but overall you don't look like you have breasts the way most of the people on this site do. Put on some muscle mass and wait until you're 19 to decide if this is something that needs to be taken care of. When I was in high school (about 5 years ago) at least a quarter of the guys had something similar to what you have.
