People with a healthy and positive body image usually feel good about their bodies, and have some bad days when they don’t feel so good.

That doesn’t mean people with a positive body image run around feeling hot every minute of every day and tell everyone else how beautiful they are. (Although that would be cool if they did, that’s not usually how it works.) It’s normal to have up and down days about your body. People with a positive body image bounce back a lot quicker and easier after a day of feeling bad about their bodies and don’t get obsessive about what to change about themselves.

People with an unhealthy and negative body image usually feel bad about their bodies and have only a few good days when they feel OK.

People who have a really negative body image have a hard time finding something they like about their body. Their bodies make them unhappy. And even if they try to make changes to their external appearance—like coloring their hair or losing weight—there’s always something else they want to “fix” or change, because their negative feelings run deeper than the surface. Sometimes, people with a negative and unhealthy body image become obsessed with their appearance.

If you or someone you know is really obsessed or preoccupied with his or her body, he or she might have a bigger problem. To learn more about eating disorders, click here.

Bodies come in different shapes and sizes (yes, all body parts!)

Worries about your sexual parts—breasts, vulva, penis—can cause a lot of angst! A lot of people at one point in their lives have wondered if they are big enough or small enough or just right. Questions about breast size and penis size are really common and a natural part of growing up. Just because you wonder if your size is OK does not mean you have a negative or unhealthy body image…it means you have a natural curiosity about what to expect about the body changes of growing up, and that’s a good thing!
