when you find someone who doesnt care if you have a six pack or a bit of podge, then you know you got a true friend. As long as you be your self with a nice positive attitude and you are polite to everyone, then who cares what you look like. personally, id take someone who treats me and others with respect over some dude with a six pack.
just ignore those kids who like to showoff their stomach, they probably only do that since their brains are the size of peas :P
I wouldn't worry about this. The most important thing is for you to be healthy, not so much how you look. Everyone has different likes and ideas for what they find attractive. My fiance has a one pack, but he is the most attractive man to me that I know because of how he acts. He is the sweetest man I know. Focus on being healthy and doing well in school. People want the whole package, not just a "hot" body. A "hot" body can't hold a relationship, but if you treat someone right, that can make a huge difference.
