Yeah agreed. I did some research the other day in an attempt to wrap my head around it. Learnt a lot about the anatomy/physiology of erection, but still couldn’t quite work out how venous leakage affecting the glans/CS primarily exactly works. I found this
The intermediate system consists of the deep dorsal vein and circumflex veins that drain the glans, corpus spongiosum and distal two-thirds of the corpora cavernosa. The veins leave the glans via a retrocoronal plexus to join the deep dorsal vein that runs in the groove between the corpora. Emissary veins from the corpora join the circumflex veins; the latter communicate with each other at the side by lateral veins and corresponding veins from the opposite side, and run under Buck’s fascia before emptying obliquely into the deep dorsal vein. The latter passes through a space in the suspensory ligament and between the puboprostatic ligament and drains into the internal iliac veins.

It sounds to me like it is probably a deep dorsal vein issue since the glans and CS seem to drain direclty into it. What I’m confused about is where the ‘leakage’ idea comes into play. Is the DDV supposed to be compressed like emissary veins of the CC are? If so then a lack of compression would case it to drain glans and CS more quickly than it should, but I don’t know how such a large vein could be compressed as such.
