My penis is 5 inches since i was 13 years old and i am now 17 and 6 month i barely have arm hair and my penis hasnt grown since. will it grow anymore?

Here are some ...: Physical growth and manhood display come to a halt soon after leaving puberty/adolescence and marching into adulthood; for most men, such turning age is roughly around age 18, but may widely vary. So, you get what you can expect according to your genetic codes from your parents together, and have to adopt and adapt to what you have so to live a long happy life. Note: A 5-inch long penis is good.

Possibly: you may have another growth spurt, but even if you don't your size is completely normal as is. Penis size varies greatly. Honestly when it comes down to pleasing your partner it is not about size. It is about being thoughtful, caring, and giving. Check in with your partner about how they are feeling and what feels good for them. Thats what counts! Also masturbating can NOT affect size!
