Depends. Are you overweight? It could just be fat. If your chest is disproportionately large (looks like breasts) it could be gynecomastia and you should see a doctor. It's not dangerous, just potentially embarrassing, but it can be corrected.
A boy can bite and suck your chest. Hickeys. And, depending on the guy, it can apparently even be orgasmic.
