Am I and endomorph, extomorph, or mesomorph?

Just wondering because I have bony shoulders and collarbone, muscular arms and calves, and chubby thighs and lower stomach. I know you probably think I'm too young to be worrying about this stuff but I was wanting to know this for health reasons. I also needed it for a survey on which sports would be best for me. Thanks for your guyses opinion!
