So what will physically change on my body?
Usually the first sign you shall notice is the enlargement of your testes (or testicles). The scrotal skin will also change texture.
Your penis gets longer and wider.
Fig: Testes and penis changes. Note that male organs come in different shapes and sizes. They are all normal. This diagram is only a guide. The 5-stage process that your genitals (penis, scrotum and pubic hairs) go through during puberty is called Tanner Stages.
Hairs will grow all over your body. You shall notice this on your face, like a beard, chest, moustache or sideburns, legs, armpits and around the penis (P). Usually it's pretty thin at first but gets stronger and darker towards the end of puberty.
Your shoulders get wider, muscles start to get bigger and stronger and you gain weight. Physically, some boys become bigger really fast. Not everyone grows at the same time or the same rate. Some people have their growth spurt really early and others really late.
You may notice that you are getting an 'Adam's apple'. This is your larynx (voice box) getting larger and sticking out at the front of your throat. Your voice may seem to be cracking, squeaking and deepening. This is normal. When your larynx has finished growing your voice will sound OK again and probably a bit deeper than before. You will begin to sound like your dad and play tricks on the telephone (don't do that)
Breasts look like they're developing a bit! (This is quite normal and usually goes away by the end of puberty)
Your body will start producing more sex hormones, so they have more feelings and more erections. You get erections sometimes because you're nervous or excited and other times when it just happens by itself! This can be a bit embarrassing at first but other people don't usually notice them as much as you do. Think of something different like a pending exams and soon the erections will vanish.
You may have 'nocturnal emissions' or wet dreams while you are sleeping. The 'wet' stuff is seamen and you haven't wet the bed! It is also a normal part of growing up because your body is starting to produce sperms.
Be ready for acne, pimples, zits, spots and stuff like that. Your skin and hair will probably become more oily. Hair follicles (where a hair grows out of your skin) get blocked by dead skin cells, and bacteria grows. The bacteria makes your skin erupt into pimples. These are usually on the face, shoulders, arms, back, and chest. They can look red, white, or black. Those little bumps and marks on your face that can make you miserable and sometimes, not even want to leave the house. Nobody likes them, but almost everybody gets them. Just try to live with it. It will all clear up after puberty.
More sweat, and stinkier sweat, are a normal part of puberty. It happens to all kids as they get older - boys and girls. It's because of those puberty hormones again. The hormones are affecting your sweat glands, and your sweat glands are making chemicals that sometimes make you smell. There are lots of sweat glands under your arms, so your armpits might be one place you're a bit stinky.
