You are worried because your body is changing.
But that’s completely normal: you are growing up.
Your body is now producing sexual hormones.
These hormones are new information for your body.
They are telling it what needs to change.
They are slowly turning your body into a grown-up’s body.
This period of change is called ‘puberty’.
You start growing hair in your armpits and genital area.
You start growing beard hair, which you can shave off or leave to grow.
Your voice changes from a child’s voice to a man’s voice.
You experience ejaculations.
That means: fertile semen comes out of your penis.
This change doesn’t happen overnight, it takes a bit of time.
And: the hormones make you feel things very strongly.
Sometimes you will feel very sad, sometimes very angry and sometimes very happy.
This is all part of puberty and part of growing up.
This change in feelings will calm down again at some point.
