k_potency

This is my unscientific theory.

Potency := limited amount of erection energy within your “system”. It replenishes some hours after fully spent.

During foreplay, if you use up too much potency, then your erection will be difficult to come, difficult to keep.

Eg illustraing 過度刺激: Even as a young husband, when I had too much “boob” play, potency was  often used up very quickly, leading to ED.

Eg: if I try no-pill for x minutes of perseverant_foreplay, i often use up scarce potency, and experience ED issues. Usually, the pill can help reboost potency, but over a relatively long period.

Eg: longer interval (lower frequency) like 2w?…. can replenish a potency “reserve”, but this effect becomes less consistent as we age. After a long interval, we often hit ED + PmE.

Eg: 2007 in Boston Tufts hospital, I was asked to collect semen, using erotic videos + magazines in a private lab. Some young men presumably had enough potency to “do it” in this very poor setting, but my potency was way too low.

— pills .. doesn’t create potency, but it can amplify/boost the energy to achieve erection.

A dwindling potency can still give erection, thanks to the magical pill

— VED .. doesn’t use up potency. Potencan can help VED do its job.

— morning erection .. is somewhat related to potency. I have regular morning erections but still experience ED when awake.

— sexual drive aka libido .. is the force behind potency, but look at young male sex workers. They don’t always have sexual drive while doing their job, but they have potency [energy].

Now look at an older playboy with multiple sex partners. He has plenty of desire but limited potency [energy].
