I am 16 years old currently and during my puberty stages I have been getting acne, growing a bit, masterbating ect. There is a thing that I am questioning though. When I look at my body my rip cage so still outward to where I can see my side ribs (From feeling self conscious and eating less) and under my ribs in the front but still have belly fat. Now I don't know if it is just because my spine hasn't grown yet because of delayed puberty or something. Also gynecomastia is still a problem (2+ yrs
