162cm is the average height for a 14 year old boy. You could be older or younger and the stage of puberty you are at willl also have a large bearing on your penis size. But a 14 year old boy might have an average penis length of 3 or 4 inches erect, obviously some boys will have a smaller erect penis than this and other might have a longer one.
Wait 4 years.
NO!
The average length of a seven-year-old boy's penis is between 2 and 2.8 inches when erect.
