exactly. Simple analogies of plumbing, rubber, creep. etc do not apply at all human tissue and is not nearly as intuitive as many people here try to make it out to be. Tissue has a response to stress that is not exhibited by any nonliving substance. Repeated stretching of human tissue, if done too intensely, results in toughening and loss of elasticity, not weakening. A PE session may temporarily damage the tissue, but the end result of the tissue response is some combination of the following depending on the exercises, intensity, duration, and other factors. The immediate response may be cell damage/death, stretching of the collagen matrix. Hours later, cells may begin to divide, restructure the extracellular matrix, secreting collagen to repair the damage and possibly reducing the ratio of elastin to collagen in the tissue. Basically the composition of the tissue changes. If you do it right and don’t overtrain, cells may grow and divide to meet the demand of the tissue restructuring and maintenance that is taking place.
I am starting to realize the importance of intensity thresholds, technique, etc. in the response of penile tissue. Much like yoga is able to stretch and lengthen the ligaments over time, PE, if done slowly can stretch the penile tissue. If done too intensely, the tissue will have a response that makes it less prone to growth, which is why overtraining is to be avoided and why deconditioning breaks are effective.
As far as an ADS is concerned, there are plenty of scientific articles that suggest static stress causes cell division and tissue growth. There are plenty of practical instances here that show this may also be true of the penile tissue.
