Why do Orange bends, ulis, sadsak slinky, horses work better for girth? My guess is that it works like this:According to wikipedia, the tunica consists of two parts - the outer tunica that is strong lengthwise but not as strong girthwise, and the the two inner tunicas, one for each CC, that are strong girthwise but not as strong lenghtwise. In all these excercises, you are not fully stretching your unit. When you are not engaging the outer tunica lengthwise, the pressure will be borne primarily by the inner tunicas alone, and only partly by the outer tunica, since it is weaker girthwise. Since more of the force is taken by the inner tunicas, they are stressed to a greater degree = more deformation.
Another way to describe my understanding this is that if the outer tunica is fully engaged, as in jelquing, the inner tunicas will be constricted inside the outer tunica; when the lenghtwise fibers are stressed, they will not be able to move sideways as easily as if they were lying loose side by side.
I think you nailed it mgus
Obends give outward pressure, where jelq gives inward pressure. Even though when doing an obend it feels allot like inward pressure.
If you only do obends and no jelqing you will notice you’re ejaculation just plop out, like it would if you only vacuum pumped. And conversely if you only did jelqs and no obends you will find you ejaculation shoot out far like it constricted.
The road to hell is paved with good intentions.
