Yes. :)
Maybe try to think of the penile venous system as if it were the Mississippi River system, which drains the entire center of the United States. In this analogy, the mighty Mississippi is the deep dorsal vein. You’ve got your little, tiny brooks and streams (capillaries) coming from all over the place (way up in Minnesota, over in Pennsylvania, Arkansas, Tennessee and other areas) which drain into creeks, then rivers, which in turn drain into the Mississippi. Many of these tiny streams drain the “skin,” if you will, in their own areas. Think of the superficial dorsal vein as maybe the Arkansas River, or the Allegheny farther north, both of which flow into the Mississippi.
Abandoning our river analogy, in the penis all these veins have to do with erectile function, even the little ones. As an erection builds, because arteries are pumping blood in, the CCs expand which causes the tunica to become tighter. The tunica clamps down on all the veins (or most of them) and keeps them from draining out. More blood comes in than drains out. If the veins in one area are not clamped down on enough that they are are leaking, the erection will not proceed farther, or will not occur at all, or will be lost after it gets up there if the leakage somewhere is sufficiently greater than the arterial flow in.
The best test we have to determine if there is venous leakage anywhere in the penis is the Doppler Color Sonogram. This simple test can pinpoint if there is leakage anywhere in the penile vascular system. In cases where leakage is moderate, but still sufficient to prevent a good erection, there are drugs which will counteract the drainage and do that well. A cock ring will usually help in moderate cases. When leakage is severe, though, surgery is the only option. Unfortunately, the surgery is not always failsafe (up to 80 percent success with experienced doctors). The condition may return sometime down the road, or not work well enough following surgery to cure the issue.
Does this help?
Meanwhile, worry less and enjoy this wonderful process more. Even though it is pretty far away, during waking hours the brain controls a lot of what happens in the penis. When you worry, you cause these surges of adrenalin. Adrenalin is a sure erection killer.
