I don't think there is any possible solution, unfortunately. Before getting PMMA, I did about a year's worth of jelqing/stretching/edging, and the only thing I gained was bout 1/10 of an inch in length and about .4 inches in girth. Mind you, my EQ and duration game were top shelf. There was hope in the $20,000 auto-stretching device on here but that quickly fizzled. The other option is length surgery but from what many have pointed out here is that you only gain flaccid length, not erect length (although, to
@Texas credit, he firmly believes that with the right routine post surgery, you can in fact gain significant length).
Remember - this is my opinion. There are other folks on here who swear they've gained doing their stretches. I would say to lurk on the other threads here about this topic, and you'll note that there are some who have been successful; in my case and several others read on here, it's just not possible for me. I've come to terms with it. My non-bone pressed and pressed are also at 5in and 6in. I make up for it in girth (6.1 this morning).
