What happens in venous leakage is this: Normally the cc chambers expand with blood and gradually press the veins (blood leading back to the heart) closed, or nearly.
When there is leakage, the erection is not complete. Or isn’t complete for long.
The symptoms are like other forms of ED. You can get an erection but it drains down before sex is done. You can get a partial, but it never becomes real hard. You don’t even get a partial, or much of one.
The reason that venous leakage is latched onto as a popular reason for erectile dysfunction here at Thunders is that it resembles so many other causes of ED. It’s an easy label.
There are two tests for it: The Doppler Color Sonogram, an easy one, and corpous cavernosogram which is more invasive and not used unless the logic of the case points toward a surgical solution. Either will indicate a leakage problem.
Erection angle isn’t an issue. If your erection is unbendable, you can have successful sex, no matter your angle. (Well, there are extremes that I can imagine.) If by 45 degrees you mean parallel to the floor, that’s where I am. It went up to about two o’clock after some years of pumping but reverted back when I pretty much quit. However, no problem with a hard-on that’s parallel to the floor for me.
