Venous Leakage Or Poor EQ?

Hello. I have not begun a PE routine yet but I have been browsing the threads here for quite some time trying to answer my questions about PE. My biggest concern is starting PE without knowing if I have venous leakage or not. I know my best option is to visit a urologist and find out, which I will be doing soon. But I have doubts that I have venous leakage and instead it’s just a poor EQ. So my question is how does someone know which is which? My erections sometimes do not last long without constant stimulation, but other times I can maintain the erection without constant stimulation which is the reason for my doubt on my own venous leakage.

The fact that you can maintain it either with or without stimulation already crosses out the possibility of venous leakage.

Why is that? Forgive my ignorance, but can you explain how that rules out the possibility of a venous leakage?

If you have venous leakage you can’t an erection, period. It’s like pouring water into a bathtub filled with holes, you just can’t fill it because the water flows out as it comes in. In the penis it means the valves that should be holding the blood in aren’t working.
