What is lost upon semen ejaculation?
As semen gives physical and mental strengths, and so, it diminishes them when it is ejaculated out of the body. It is as simple as that. Though, it also depends on individual body strengths, some have genetically weaker bodies, and some have a strong body. It also depends on how much time a person gives his body to regenerate semen or how soon he is masturbating again and again. Semen energy works both ways, if one keeps using it up in masturbation it can call for trouble for that person. But if it is restrained and channelized in other areas (like keeping busy and trying to improve various mental and physical skills) it can bring extraordinary and positive results in such person’s life.
The post-marriage sexual experiences of the person not masturbating before marriage can be extraordinarily wonderful and pleasing that regular masturbator can’t even imagine. When semen drains out of the body it depletes the key elements from the brain also, which can cause various problems like headache, reduced thinking abilities, recall abilities, forgetfulness, lowered ability to concentrate, unable to focus for long, getting mentally tired or impatient quickly, etc. So as soon as erections start occurring from puberty, one shouldn’t haste to do masturbation or ejaculate semen, keep that desire pending for future, now is not the time, there’s a lot of work that semen has to do for you first and so don’t ‘waste’ it or disturb it for the good that it’s doing for you.
