I’m assuming you mean erect. The average penis size for an adolescent is 5″ and the rest its 5-6″ so your ok. My size is 5.75″ and I’m 18. I’m not going to lie to you and say size doesn’t matter, because it does. You stop growing at around 22 so don’t worry. 5″ isn’t bad. It’s not completely size though, its the duration and skill too.
The only way I know of enlarging is through surgery where they cut a piece of flesh holding your penis in. It’s located above the base and inside, when they slice it, you gain an average of 1-2″ because the part of your penis outside of your body is about 1/3 of the penis

yea i guess thats normal i had the same problem worrying about it but everyone says thats the normal size and thats all you need to satisfy most girls.unless shes a super loose whore you should be okay

A day cannot go by without at least one penis question.

Stop worrying about before I come to your house and cut it off

yah that normal

At your age, by the time you reach the age of 21, you still have a good change for your penis to be about 5 and a half or more, which is a normal size for a man. I mean normal size that sensible ladies accept.
Big size are ego boaster, but not the only mean to the end. Whatever size you will have mostly depends on your genetics inherited from your parents or your ancestors. So, whatever size you are “gifted” there are other better ways you can make yours better. Master the art of making love. Learn art and techniques from those experienced friends or good books you can find. It is not only the size that really matter when you have sex with someone, but is it the art of what you do before putting yours inside hers and what you will be doing while yours is inside hers, that she will long remembers and cherish! So, if don’t have that “endowed” size you have been wishing, master the art of making love, instead!
