Apologies— I didn’t get the editing done in time:
I’m a little worried about the accuracy of the results. I never read the first post until after I’ve voted (if at all), so if most people are like me in that respect it might be worth noting that the results might be a little skewed (since the title of the thread doesn’t specify the poll is for length-gains). At time of writing, thirteen people, who might also have voted for jelqing because of its benefits for girth, voted for clamping. Others besides those who voted for clamping may also have voted for jelqing due to the girth-increases they’ve experienced.
At time of writing 49 people voted for simple manual stretches and a total of 61 voted for wet and dry jelqing (40 and 21 respectively), all of which are techniques associated with newbie PEers (and, in the case of simple manual stretches, performed mostly by newbies) of which there are probably more on the forum then there are senior members more inclined to continue the pursuit of length gains through the use of equipment and/or advanced techniques. Also— newbie forum members are specifically instructed not to try other techniques, and generally get the fastest results as a result of the much celebrated newbie gains. Those just transitioning, and recently transitioned, from simple stretches to advanced techniques may also vote for jelqing and simple stretches because they associated them with their faster newbie gains.
Apologies if I’m raining on the parade, but I think there’d need to be more controlled conditions and more specific questions to yield worthwhile results.
