What's the lowest effort PE method which actually works?

I am still unsure how much of a PE method fails because the person involved simply doesn’t respond to it physiologically, or he is performing it inadequately (technique, frequency, and intensity), or a combination of both?

Like what makes a hard-gainer a hard-gainer versus the anomalous shooting stars that get crazy gains in just their first year?

Regardless, I found the following routine help me gain a whole inch in erect length (and improve EQ). I should note, I was in my 20s so that may or may not have had an influence (??).

1. Get into a hot shower and do light-to-medium manual stretches. Forward, up, down, left, and right. Enough tug to feel tension but not enough to injure. Physiological Indicators (PI’s) folks, it’s a topic found on Thundersplace essential to understand for your success (and avoiding injury).

2. Then with the assistance of the hot water from the shower, would perform wet jelqs.

3. If an erection is achieved, start edging/ballooning (maximizing glans engorgement in addition to shaft engorgement).

4. Repeat the process for no less than 15 minutes, and no more than 30 minutes. Any sign of "fatigue" or "pain" would be an indication to lessen intensity or even stop.

5. Do not ejaculate. If necessary, wait till much later in the night to achieve your climax. Try and avoid porn and use your imagination, or an erotic still image (like a hot model in an erotic pose). If you need a jump start badly, use porn as a last resort, and watch it long enough until you’re hard and exit the screen. If you find you can’t get hard at all without porn, you’ll need to address that first before adequately succeeding in PE.

So basically a manual stretching + wet jelqing + ballooning/edging + no climax in a hot shower routine in about 6 months gave me an inch of erect length if memory serves me correctly. Seeing’s how no devices are required, and how you inevitably will shower, this is as "low effort" as I can muster that also yielded tangible, measurable gains.

What I do now is stretching my member under a stream of hot water manually for 5 minutes. It is absolutely perfect once you reached your limits.

For a start you could do the same thing every 3 days I would say.

I think a light 1-2 lb ADS which progresses over months is probably the easiest. I’ve read from other members that gains are sort of on the slower side vs hanging.
