I think i have unusually large ribs
Several years ago, I began to notice my ribs stick out further than the people around me.
If I lie down flat on the floor, I am unable to see my feet if I stick my head up, my ribs will stick out about a handbreadth from my shoulders, more for the lower ones. (They don't stick out of my skin for anyone who thinks they're funny)
It makes me look rather fat, which coupled with my skinny arms and legs, just makes me look odd.
I am a guy, if anyone asks, so I do not have breasts.
