Young boys cannot ejaculate. A boy's first ejaculation usually happens about one year after he begins puberty , which is when his body starts changing into a man's body.  Most boys go through puberty in their teens. The first time a boy ejaculates usually happens when he is asleep. This is called a nocturnal emission (which means "an emission happening at night") or a wet dream . It happens without the boy's control, often when he is having a dream about sex.  Scientists believe that wet dreams are the body's way of removing too much semen. [ source? ] When a boy begins masturbating , wet dreams usually stop happening.
