Ejaculation
When you have an orgasm, you ejaculate. Semen comes out of your penis through your urethra. We call this ejaculating, coming or discharging semen. This usually happens in 3 or more squirts and lasts for a few seconds.
First ejaculation
Most boys have their first ejaculation between the ages of 11 and 16. From that point on, they are sexually mature and can get a girl pregnant. A boy may have his first ejaculation from a wet dream, but not necessarily. You can also have your first ejaculation when you masturbate or when you make love to someone.
Wet dream
A wet dream is a spontaneous ejaculation a man has when asleep. If you wake up and the bed feels wet, you may think you’ve wet the bed. That’s not right, you’ve had a wet dream. A wet dream happens spontaneously, often without dreaming about sex.
Wash but don’t use soap
Wash your penis every day. Pull your foreskin back. This allows you to clean under the ridge of your glans. If you don’t do this you get smegma under your foreskin. This white, sticky stuff may smell, irritate or cause inflammation. Keeping your penis clean is also important when you are circumcised.
Peeing
Semen and pee never come out of your penis at the same time. When you have an erection, your urethra is closed off. If you have to pee, you need to wait until your penis is limp again.
