Body image is a person's opinions, thoughts, and feelings about his or her own body and physical appearance. Having a positive body image means feeling pretty satisfied with the way you look, appreciating your body for its capabilities and accepting its imperfections. Body image is part of someone's total self-image. So how a guy feels about his body can affect how he feels about himself. If he gets too focused on not liking the way he looks, a guy's self-esteem can take a hit and his confidence can slide. (The same thing can happen to girls, too.)
