In my experience, semen retention is never about the retaining of the semen but about Jing and Chi energy retention.
And not just about retention but about a healthy flow and circulation of those energies through the body.
Which is exactly what KB does.
Most guys in SR communitity don’t get this and think it is about the physical semen only. And while semen represents a certain amount of stored Jing energy, it is not the main storage area of it in your body. Most guys are usually so depleted of Jing, that when they start to conserve it, that Jing is first mostly stored as semen, before it massively accumulates in the lower Dan Tian and in the kidneys.
After 11 to 30 days your balls are usually full of semen, then the extra Jing starts to accumulate mostly in the lower Dan Tian, giving that aura and presence boost.
Without a ton of Jing, Chi and a healthy energy circulation you will not get that magnetic aura. For magnetism, your energy channels and that flow of energy are much more important than your semen.
If you have a lot of Jing reserves, even if you release semen, your body will take Jing from the lower Dan Tian reserves to regenerate that semen, while keeping the magnetic aura up because there are so many reserves. Only when all that Jing from all the reserves is depleted again, you will have the effect again that “semen retention” equals having any magnetic energy at all in the first place.
As a man one should still not ejaculate semen too often, as an orgasm triggers prolactin, which can give brain fog for a few days.
Additionally, an orgasm shocks the physical nervous system, which depletes Ojas energy.
As a women one shouldn’t orgasms too often either, as the nervous system shock during orgasm will deplete her Ojas reserves here too.
Since the energy channels (meridians etc.) are heavily conneted to the physical nervous system, I believe that adding the new nervous system scripting to the next iteration of KB, will be likely the most important thing to upgrade.
If you are male with a strong nervous system, AND charged up energy channels, the women’s nervous system will subconsciously read that information and feel heavy attraction for the POTENTIAL of the man. Potential is attractive to women, because it determines what impact that man is capable on inflicting onto the physical world, and thus, ensure success and survival. Hence why the girl in the video says that she can be her most feminine in the presence of such a man.
