Mechanics of erection vs. Uli
Perhaps someone can explain why when the ULI thing is applied, the circumference of the penis increases significantly beyond the unaided erect size but yet it is not as hard?
Logically, the size should be dependent on the internal pressure. Since the penis is hardest with a unaided erection, it follows that the internal pressure must be higher than when using the ULI thing. Yet the penis is larger when using the ULI thing, despite a lower internal pressure.
Must be another mechanism at work here…
