My friend told me that he ejaculated. What does that mean?

Boys and men can ejaculate.

That means that fluid comes out of the penis.
This sometimes happens during sleep.
Or when a boy or a man rubs and strokes his penis.
And it happens mostly when a man has sex with someone else.

The boy or man will experience a great feeling when he ejaculates.
That great feeling is called an orgasm.
Most fluid comes out of the penis at the moment of orgasm.
Some fluid may also come out of the penis before orgasm.
From puberty, this fluid contains sperm.

Sperm can become a baby together with an egg.
The egg is found in the woman’s -> womb.
The penis sometimes enters the woman’s womb during sex.

Ejaculation is not bad.
Men and boys experience it as a good feeling.
Most boys and men ejaculate a lot during their lifetime.
Men should always use a -> condom to avoid “accidentally” making a baby.
A condom also protects men and women from contracting certain diseases.
