Guys have these sometimes.  They are normal and no big deal.  

Once a guy reaches puberty, his body will constantly produce sperm.   If a guy has sperm building up in his system, his body will just need to release it from time to time.  When he sleeps, his body may release this sperm (ejaculate) without him intending to and he wakes up to wet underwear.  Maybe something he dreamed about triggered this physical response.  Maybe not.  Doesn’t matter.

Afterward, his testicles are empty, ready for more sperm to be produced.

Another way that the pressure of sperm build up can be alleviated is to masturbate. 

Now, something interesting to think about it this:  A man, who is deciding to wait until marriage to have sex, may also decide to not masturbate.  Instead he relies on his body to have wet dreams from time to time.  This choice may help his body to produce sperm at a slower rate, resulting in the need to ejaculate less often.  This means less urge to masturbate.  And maybe even fewer wet dreams.

Fast forward to the day the man gets married.  He has sex with his wife. 

Let’s be honest.  They have sex a lot.  They hardly leave the honeymoon suite.

His testicles are getting emptied pretty often.  This triggers his body to make more…and more quickly, so his body can be ready for the next time they have sex.

So the old saying “If you don’t use it, you lose it” is just not true. 

A man doesn’t need to keep up with his need to ejaculate by masturbating.  He is not going to lose the ability to have sex.  In fact, masturbating may make a man’s body thinks it had better hurry up and produce more sperm, so his choice for abstinence could be more stressful than it has to be. 

The truth is that a man’s body will naturally do some adjusting to his circumstances—whether time of abstinence or sexual activity.
