Question:
Hello,
I’m currently 17 years old and still at Tanner Stage 4.5. When it comes down to my penis girth, I don’t remember the last time when it has gotten bigger. My penis girth is at 5.1 inches and from my knowledge at my Tanner stage my penis length should not increase significantly which is fine by me. But since my penis girth has stagnated for quite some time now (since Tanner stage 4.0 or less) and at my Tanner stage the penis is expected to grow thicker, which hasn’t happened for me yet, can I expect it to grow a bit? And if yes, could you give me some numbers?
Answer:
The typical adult male’s fully erect penis is anywhere from 3.5 inches (9 cm) in circumference to 5.5 inches (14 cm). The average circumference when fully erect is 4.6 inches (11.5 cm). Therefore, you are already larger than the average adult male. It is likely that you won’t get significantly bigger at this stage of your development.
The amount of growth for a person’s penis is not very predictable. Penis sizes vary a lot between individuals, just as shoe sizes or ear sizes vary, thus making each person unique.
