Welcome, brother. Great user name. Sorry about the laughing emotion. It's more for the name than the post itself. Nearly lost my mouth full of coffee. My wife used to joked the same way, when she wore her pants, and said, "Pants, without the -ies."
Let's dive in for your situation.
I have been using the pro-extender device for stretching for less than a year and I use it for two weeks every month for three hours a day. What happened is that the ability to stretch while wearing the device increased greatly gradually, even after stopping for two months. The flexibility of the penis gained thanks to the device did not decrease.
As brother
@huge-girth indicated, you need to wear at least 4 hours a day by itself, but that's just to start the tissue breaking processes. It hasn't even start the process to repair, gap creation, and cellular development to fill those gaps yet. It has been discussed here extensively, going back far since this site was established. The glorified promises the manufacturers made did not provide evidence of gains vs time spent on wearing under specific traction load or force (the minimum and maximum pull offered by the device's spring set with the body). If there's no spring in there, it's based on the pulling strength of the unit pushes against your body. To reduce the initial 4 hours of starting time, we always encouraged to perform manual stretches, or with mechanical assistance from fulcrum base devices like the
Length Master. That breaks the tissues down faster, and reduces the total time wearing the extender to provide effective healing and solidifying the gains faster. 15 to 30 minutes with initial stretching using hands and devices will only need 4 to 8 hours on the devices, rather than up to 12 and 16 hours.
I set the device to its maximum length and my penis stretches to the last limit of the device, but when erect it is the same size as if I did nothing.
This is the worst thing you can do using an extender. If you are starting out, never, ever, uses the device at full strength. If your penis did not go through the transition period, starting at
2.5lbs, with increments of 0.5lb every 2 to 3 weeks, you can hurt yourself very quickly. Too much pulling
static force (being pulled constantly) going past 2.5lbs can cause the nerves and blood vessels to rip and tear, resulting in server damages. This is why we encourage the manual stretches using hands and devices first in a
dynamic fashion to stimulate the body to
adopt the stresses first. Notice how I bold and underline the key terms.
Is there an expert here that I would be grateful to tell me what is happening? Why does it stretch all this way and not get erect big?
Most of us who use extenders here have enough experience in using them. We can't call ourselves experts, but we have sufficient knowledge in the past 20 years to offer insights based on collected data on gains, usages, and management of methods for every specific case. In your case, you maxed out the device's capacity too fast, too soon, using it too sporadically without a set routine. The body rejected the gains because the body did not have enough time to adopt to the changes and cement the gains.
So, going forward, let's redo the approach using the extender before the penis loses its
malleability and
pliability to use for growth. Let us know your time you can dedicate to PE, and the few extra things you need for length routines. Example, a bit of extra cash to grab wraps, an assisting device for manual stretching because you need to go past your hands' strength for specific stretching exercises, and supplements to boost your bioavailable resources the cells need to repair and reproduce for growth if your dietary intakes are not at their best.
