Why is my penis only 5 inches? I'm 16 I'm 5'6" and I've never had any serious medical problems. Why is it that after 16 years my penis is only 5 inches? I hit puberty really late. My voice dropped when I was about 14, I  finally grew leg hair when I was 15, and even though I still don't have any facial hair I have a lot of pubic hair.
