Unlike ttt, I don’t believe that the tissues outside the tunica have any affect on pressure transmission, until they fill with edema fluid (that is they become edematous; like the Michelin Man).
Reconsidering, I think that you are right. Fluids are incompressible and inextensible, which - physically speaking is the same. Edema formation actually decreases the pressure in the sealed tube due to the volume expansion, but as long as you keep the pressure constant you will maintain the pressure gradient, even in the presence of edema formation. Saying that, I must also say, that Mr.Happy was right. Hear me, Mr.Happy?
That, however, would upgrade pumping a lot in my opinion, since the pressure gradients can be quite high. Intuitively, I still favor clamping. May be because my gf complains about the fluffiness of my dick after heavier pumping. This (edema, doughnut etc.) never occurred with clamping.
It is very satisfying to state at this point that we (I at least) are gaining a higher level of understanding the physics and the biology that stands behind pe and allows us to make our dicks bigger. In that sense I am not unhappy to err from time to time. Rather, every error proves that it’s not a waste of time to hang out at ThunderSS’s and discuss these issues.
Thank you all for discussing and..
.. Happy new Year
Later - ttt
