Some boys are eager to grow facial hair as a sign of manliness. Others do not want it and prefer to shave from the first moment it appears.
Some boys worry about penis size, especially if they start growing later than others. Other boys who started growing earlier may even tease them about how unmanly they are. Before getting upset, it is worth remembering that no one has a grown-up man’s body before they are 18 or 19, so there’s no point being worried or ashamed.
Pubic hair appears on boy's bodies around the penis. Body hair grows under arms and on the chest, legs, arms, and lower half of the face. It does not all happen at the same time - and some boys will be more hairy than others, even when they are fully grown.
There are changes to boys’ bodies that are less dramatic. As with girls, boys’ faces become more “pointy,” as the skull beneath changes shape and creates adult features. Boys’ chests may also bulge at this time - instead of breasts, these bulges are the beginnings of pectoral muscles. legs and feet often
grow at different speeds than arms, so feeling gangly and clumsy is not unusual.
The hormones released at puberty help build muscles in young men.
