Question:
How fast does the penis grow per year?
Answer:
The rate at which your penis grows depends on what point you are in your development. See the discussion on penis growth for details. In stage 3 your penis will grow more quickly in length, but in stage 4 it will increase in circumference. Most of the fast growth occurs about the same time your body speeds up its growth. However, I can’t tell you exactly how fast any one person’s penis will grow in a year, just as I can’t tell you how fast you will grow in the upcoming year. If you are just starting your growth spurt, I can tell you that you will grow faster than you have been in the past, typically twice as fast as you grew in the past, but I can’t say the exact rate or amount for any one person. To estimate what stage of development you are in, see the Tanner Stage Calculator for Boys.
