How big is my penis soupposed to be at the age of 15 im 3.6 inches when not hard and 6.8 inches erect? -
So you-re what is called a -grower- (versus a -show-er-)
This is a good thing and your size is excellent.
The average figure is about 9.5cm (3.75 inches), but this kind of precise measurement is rather valueless. Many factors can cause a temporary shrinkage of two inches or more, for instance cold weather or going swimming, so you needn-t worry if you happen to fall short of the average figure.
Good Luck - God Bless
Don-t be worrying about your size.
Unless you-re actively having sex, what does it matter anyway?
Chill, find a lady that actually likes you, and voila. It doesn-t even matter anymore.
(By the way, your measurements are as nice as mine, and I-ve been called -well-endowed- by every lady I-ve messed around with. Oh, and I-m 17.)
Average ERECT is 5 to 6 inches! So you-re a good size. Thats actually bigger than the average adult male so congrats! Hope that helps!
you are already like, bigger than the average grown man
