Skin and spots
For many boys, adolescence is a time when your skin begins to get oilier and produces more sweat. Sometimes this oil can block your skin pores and hair follicles. This causes spots, or acne.
If you get spots, use a skin cleanser to make your skin less greasy. Don’t use ordinary soap. It dries your skin out, so the skin reacts by producing more oil - leading to even more spots.
During puberty, hair starts growing in different places.
You may grow a mustache or a beard. Hair also starts growing under your armpits, around your penis and anus, and on your testicles. Some boys may grow chest and back hair while others may never grow any at all.
It all depends on your genes. Some people are hairier than others. And on’t worry if you can’t see any new hair growing yet. For some boys it starts when they’re 11, but others don't start growing hair until they're 15 or 16.
Around the age of 14, many boys have a growth spurt. This means you get taller, and your chest an shoulders also get broader.
Girls start growing earlier than boys, usually when they’re about 12. Before you have a growth spurt, it’s common to put on some extra weight around your belly.
Many boys find they have swelling under their nipples, so they get enlarged or swollen breasts. This is normal. Some boys may experience tender or painful breasts. Also, one breast may be larger than the other.
Even though it’s common, many boys find it very embarrassing. Luckily it usually goes away within a year or two, once the changes of puberty have finished.
Penis and testicles
Your penis and testicles grow during puberty. First your testicles get bigger, then your penis. Your penis gets thicker, an then grows longer. In most boys the penis has reached its full size by the time they’re 15.
During puberty, you sweat more, especially under your arms. This means you’re likely to smell of sweat more. It’s perfectly normal.
Just wash every day and wear clean clothes. If you like you can also use deodorant.
