Antidonut for packed pumping
Hi friends
I´ve only been using a pump for 2 weeks so far, but I´ve already observed something interesting
An antidonut does more than prevent the swelling of the upper shaft.
It also concentrates the pulling force in the glans when the tube is packed, creating a noticeable superior pulling force.
Without the antidonut, a lot of the vacuum forche is cushioned by the ballooning upper shaft skin.
I achieve a superior lengthening with the antidonut, noticeable by 2-3milimetres above the max i reach without antidonut.
This is significant when aiming to create a good % of increased stretch above BPEL.
Also, when the tube is packed, a lot of friction is created by the walls of the tube, because the skin is being pushed against it, and that´s enough to hinder the longitudinal pull force enough to frustrate optimal length work. When the skin is massively swollen, that fluid augments pressure and the workout becomes less and less effective and less and less unpleasant.
Lubricant doesnt seem to reduce the friction enough, and using a bigger tube would only create more space to be filled by fluid girthwise, til the situation is back to the same.
This becomes worse at high pressure to a point where a LOT of the pulling force is detracted from the pulling force because of the increasing pressure.
In this regard, even low pressures may be more indicated for length work
I feel I could benefit from a ultra reduced friction and improved antidonut.
