I’m new to this thread and I’d like to summarize my extender use, gains and some observations.
I’ve been consistently wearing a penis extender since January 2014 (about 14 mos.) and have made some pretty good gains. My prior PE was limited to on-and-off jelqing that I began about 6 mos. Before using the extender, which gave me some more width, but little or no length gains.
I wear the extender 6-8 hrs a day, 6 days a week and have been consistent with that routine, with the exception of 1 or 2 weeks that I was very ill and took a few days off. I usually wear it for about 1-1.5 hrs, take it off, let my penis relax 10-15 minutes, then put it back on. Typically, I work it like this for 4-6 hrs in the morning, and do a couple more hours at night before bed (shorter overall session).
I wear a strap that came with extender. I use a foam ring and unusually put a thick cock ring (more like a band, called a Titans Men) over the foam, under the glans. This gives a snug fit and I figured it out by trial and error. I sometimes rub the band with weight lighting chalk (that has some resin in it) and it makes it really grip, but I advise against putting that chalk on penis directly; I did, and it irritated me.
I am unsure how to quantify force or tension, so I simply lengthen the side screws as much as I can. I add bars to the arms as often as I can, always trying to push my penis length in the extender.
I never sleep in the device and remove it if something appears to be amiss or it feels wrong.
Gains: I measured my penis initially along its side, erect, without pressing in. I started at 6 inches. Now I am 7 7/8 inches erect, identical measurement type. I am about 1/4-1/2 inch longer pressing the ruler into body, but didn’t take any initial measures that way. In summary, I gained just under 2 inches in a little over a year.
I think the rule of thumb I’ve read about I.e. 1000 hrs equals an inch in gain, holds for the first 6 mos. To one year. Since about August 2014 my gains have really slowed down despite consistent use, and do not want to wear an extender for more than 8 hrs a day. I think my penis is growing accustomed to the tension that device can provide. I am going to switch to another PE routine for a while (probably hanging), but feel very positive about my use of the extender.
