Stretching exercises are more likely to be permanent compared to expansion exercises, i.e jelq, Uli’s, horses etc. Stretching exercises partly work by pulling the internal penis out and partly work by strecthing ligaments longer. Just as an ear won’t shrink back once it has been stretched for years, so too I believe, ligaments won’t. This would allow for permanent gains because the internal penis having been pulled out, can only be pulled back inside if the ligs shorten and pull it back to it’s original position.
Jelqs, Uli’s, horses etc, work by expanding the tissues to greater sizes, via blood pressure. These gains are partly from better circulation and blood pressure and partly from having grown more tissue over time from the effects of the first two. The blood chambers inside the spongy tissues are enlarged from their previous state. Inorder for all humans to get an erection, the blood pressure needs to increase in the penis, so that the chambers become rigid from being stretched to their capacity with blood. Gains from this type of growth are more easily lost, due to them being reliant on enough blood circulation and pressure to fill the enlarged blood chambers to full capacity.
Japp may find that his gains come back very quickly if he resumes jelqing. Losses in size from this type of growth might be reliant on there not being enough blood pressure in the penis to stretch the enlarged chambers full. Increasing the blood pressure would quite possibly see the gains return quite quickly. The chambers might have lost some of their elasticity from lack of ever being stretched full, but elasticity would return over time once the jelqing was contrinued and the chambers were stretched full regularly.
In short, gains from jelqing, Uli’s horses etc, are dependant on atleast some maintenance, inorder to keep the blood pressure high enough in the penis to fill the enlarged chambers to their full capacity.
Gains from pulling the internal penis out, do not require maintenance once cemented because the ligs stay stretched once stretched and do not rely on extra blood circulation to retain their length. The longer external penis does not require extra blood pressure to sustain the extra size, due to no actual penis having been grown as such. The new external length not needing extra blood pressure, as it was always filled with blood during erections, when it was part of the internal penis and nothing has changed just because the internal penis is now external.
Hope that makes sense to you. It is just theory. It still certainly leaves many questions unanswered.
There is one thing stronger than all the armies in the world: and that is an idea whose time has come.
