why do boys and men get 'wet dreams'?

What Is a Wet Dream?

A wet dream is when you get an erection while sleeping and ejaculate semen (the fluid that comes out of your penis during orgasm). It can happen with or without a sexual dream, and sometimes you wake up right as it happens. Other times, you don’t even realize until morning when your underwear, pajamas, or sheets feel damp. It might be confusing or even embarrassing at first, but don’t worry—it’s completely normal.

Is It Messy?

Semen isn’t harmful to your skin, clothes, or bedding, and it won’t leave permanent stains. When it’s fresh, it feels slippery and slightly sticky, but as it dries, it can become a bit crusty with a whitish or yellowish residue. It also has a distinct smell—not necessarily bad, just unique to your body. If you experience a wet dream, just wash your underwear, pajamas, and bedding like you normally would. Keeping clean is part of feeling fresh and comfortable, so it’s a good idea to wash up regularly.

Why Do Wet Dreams Happen?

Your body is always making semen, storing it in small sacs called seminal vesicles behind your bladder. Eventually, when these sacs get full, your body naturally needs to release it, a wet dream while you sleep.

Even if you don’t have a wet dream, your body slowly releases small amounts of semen through the prostate when you pee. So, whether you notice it or not, your body takes care of things on its own.

How Often Do Wet Dreams Happen?

If you don’t masturbate and ejaculate, your body will naturally clear out the semen through wet dreams. Some guys have them two or three times a month, some less often, and others more frequently—especially during puberty when testosterone levels are high. Every guy is different, and there’s no “right” amount.

Should I Be Worried?

Not at all! Wet dreams are just your body’s way of keeping things in order. It’s not a sign of anything wrong—it’s actually a sign that your body is working exactly how it should. Sure, it might feel awkward at first, but once you understand what’s happening, there’s nothing to stress about.

Just clean up, move on, and know that you’re not alone—every guy goes through this at some point. It’s just another part of growing up!


  • An erection is when your penis enlarges and gets hard when blood flows into it through arteries but the blood flow gets restricted by veins inside the penis so that the accumulation of blood increase the size and the length of the penis.

  • Ejaculation is when you experience sexual pleasure in and around your genitals and reach a sexual climax. Semen is then released out of your penis through multiple contractions of the prostate gland and other muscles inside the groin area. Thus (about 8 to 16 contractions) forces semen out of the penis.

  • Semen is the liquid that contain sperm cells. Semen is the actual fluid that a man ejaculate from his penis and it is a combination of about 65-75% seminal fluid, (nutrients and proteins) 25-30% prostate fluid, (liquid excretion from the prostate) 1-5% Cowper’s Gland fluid (detergent, anti bacterial and lubricant) and only about 1-2% sperm cells.

  • The prostate is a walnut size gland just below a man’s bladder. It has the ability to open and close the urinary tract (tube) and open the seminal tract (tube) connected to the seminal vesicles. The prostate help with contractions during ejaculation when it forces the semen through the urinary tract and out of the penis.

  • The genitals consist out of the penis and scrotum sack that hangs between a man’s legs.

  • The scrotum is the skin bag that hangs behind your penis and contains two testicles. The testicles produce sperm cells. Sometimes men were born with only one testicle inside the scrotum sack. Don’t panic if that’s the case for you, because it will not affect your manliness or your masculinity and you are no less a man. You will also be able to conceive children and live a normal life. If it does bother you, you might consider an artificial testicle implant.

  • Masturbation is when a boy or man stimulates his genitals for sexual pleasure and usually to the point of a sexual climax and ejaculation. Stimulation can take on many forms of action, movement, rubbing or stroking of your penis so that it produces sexual pleasure.
