I tried manual PE for about 7-8 months, only difference I saw was slight increase in
Flaccid which would go away after I stopped stretching for a few days. I know people react differently to manual PE, but if the majority of them have no good measurable results, Then there is no return on investment! why bother I say ?
I also have never read or seen an actual verifiable account of any one gaining and maintaining 1\"-1.5\" increase in length. The only two the I trust who have seen some results are Messageman and Miracle. So we have 2 out of many.
I am talking generally speaking here. I am sure there are the very few cases, but these few cases will not help the many cases where guys see no results!
Of course everyone must try their own way to find out for sure!
