PE and the Changing Tunica
Bib wrote: “Collagenous tissues under stress have been proven to increase in density, including thickness. The tunica walls will get thicker, not thinner. That is one reason gains slow over time.”
I believe this is a crucial distinction for those who fear tunica thinning as a result of PE.
The soft, spongy tissues of the penis (corpus cavernosa, corpus spongiosum) are what fill with excess blood during erection. Actually, the blood continues to circulate, it’s not truly “trapped” in the penis (unless we manually trap it with our hand or a cock ring, etc.). But the rate of arterial in-flow is greater than the venous drainage, hence a “hard on.”
These tissues are normally what we target in exercises like the jelq, holds, ulis, etc. - since it stands to reason that the more blood our cock can hold, the bigger our erections will be. But the spongy tissue is not that difficult to “work,” nor is it the limiting factor. Enter….
This is the tough, fibrous band which encircles the spongy tissue. It is dense & resistant to stretching (it has to be). Think of the tunica as a sheath, or a conduit for our spongy tissues - which are soft & swell with blood, but the tunica is what maintains erectile rigidity and shape - think of it as a “mold” into which the softer erectile tissues fill-out.
When erect, our spongy tissues are sort of a “hard on within a hard on.” We need that soft tissue for expandibility, but we also need that tough sheath for firmness & form.
I suspect that the spongy tissues of the penis are more similar between men than is the tunica. Just as some men have really thick tendons & ligaments (compared to others), I bet that some men have a much more stubborn tunica than others. This could account for some of the differences in gains - in addition to the LOT theory.
Does the Tunica Thin or Thicken
Some men have expressed a concern that PE will cause their tunicas to thin out; however, I feel that Bib is correct in saying that “….The tunica walls will get thicker, not thinner. That is one reason gains slow over time.”
Even though my penile volume has increased a significant 64% since beginning PE (6.12 x 5.2 = 13.17 ci, to 7.2 x 6.14 = 21.60 ci), my erections are actually firmer now, and they are uniform and straight.
If the tunica really was thinning out, the pressures from the swelling spongy tissues would begin to reveal deformities (bulges) in the shaft, uneven erections, etc. Also, I don’t believe there would be the same pressure buildup with the tunica - i.e., my erections would be softer as my penis increased in size (if the tunica was thinning out).
As I said, the opposite has happened for me: bigger penis = harder penis. This would not be true if the tunica were thinning or weakening.
