I’ve been looking for how penis keep blood. I found that penis hasn’t valves to keep blood but it keep blood through a muscle which compress all veins at the base of the penis, and other mechanism augmented diameter of veins that supply penis with blood while return veins are blockaded by decrease of their diameters. Jelqs can’t hurt any valves because ain’t valves
What do you think? Valves or muscles and diameter changes? And if valves exist, how I can avoid damage from jelqs?

There is also a chemical component to holding the blood. The smooth muscles are contracted while flaccid and open while erect through NO- nitric oxide. But it seems through jelqs, clamps, pumping..PE you can fill the spaces with blood without the help of NO.
Which muscle compresses veins at the base of the penis? Its the ischiocavernosus muscle, right?
Role of the ICM in Corporeal Congestion and Erection ” Meanwhile the ICM, inserting in a “belt” form across the proximal part of the 2 corpora cavernosa, presumably acts on contraction as a constricting band that appears to compress the deep dorsal vein of the penis. This seems to hamper the cavernosal venous return, and thus, augments penile erection.”
