Yes 10cm is more or less 4 inches which is pretty average for a 14 year olds erection.
I'm 15 and have a 6 and a half inch penis, it's above the average. An average man's penis is about 6 inches
No
It is normal for you. Everyone is different. If you are measuring the top side, you are far above average for any age. If you are measuring the underneath side then you are still above average, but a little more common.
No
no, it's much larger than normal for that age
No this is perfectly normal, average size for an adult male for 14 your hanging like a horse! Thats big for only 14...
Depends on your body build
Most boys start ejaculating between 12 and 14 years old.
No better get it cut down a bit
There is no 'normal' size. It varies depending on the person. 6.5 inches is in the normal range for most males.
cool story bro
yes...that is normal....It's larger than average but don't worry. most women like them bigger rather than smaller
