Wet dreams are not very healthy.
Generally, it spolis one's health and constitution in the long run.

It weakens your health. That's why having too much sex is not very
good for the body. Cos' one could notice if a person ejacuate too
much of his body's reserve over a period of time. One suffers
giddiness, blurrin eyes, breathelessness, and weak
mind...etc..
As our body ages and weaken over time.. Do notice we are not as
like before that we could have sex 2-3 times a days in those
younger time. Therefore, relentlessly masturbating, sex , wasting
of one's body reservce during early days tend to have "yang wei" or
other malfunctions later. This can be seen in men in the late 30s
to early 40s nowadays.
Boy18 fear and hatred of wet dreams is a good sign. If he
understand the insights to the above. More he should know wet
dreams are not good if he encounters too often. There is such
things that if the sperms are not used, they should be absorbed
into our body.
You should clear your mind and heart and not to think of the
opposite sex too much. This should help. I tried not to be too
obvious. Ask your heart, If you think too much, at nite you will
dream. Be truthful to yourself
