I have chest hair and want to shave it... ?

I am 15 male and have lots of leg hair, and pretty much everywhere else. I went to camp and it seemed like most of the guys shaved their stomach/chest hair. I personally don't like it, so I thought bout shaving it all except the part that goes up to the belly button. I don't have much chest hair but noticeable. If I do this, it will be my first time and I don't want it to look stupid. Any suggestions? Is this normal and should I do it?
