The question

Dear TeenHealthFX,

Hello there I am currently 12 years old, and I have a question. Is 6in while hard above average in penis size for a 12year old?

The answer

TeenHealthFX would like to begin by stating that it is normal for teenage boys to question the size, shape, color and overall appearance of their penis. Throughout puberty and teenage years, the penis is still developing; and no two boys will go undergo the exact same growth spurts and development. The average adult penis size is between 5 and 6 inches when fully erect. So, to answer your question your erect penis isn’t above average. It’s important to remember, the size of a guy’s penis is determined by genetic traits that he inherits from his parents – just like we inherit our height, eye color, and skin tone.
