I`ve already penetrated my date with a fully pumped dick, which is 7.28 in girth at max. Which went fine after a minute. The routine I do makes my penis expand from 5.5 to 7.28, at most. So when maxed out I am thicker than shane. So from my natural size 5.5 to 7.28 would be 1.78 inches in expansion in one intense session.
Yes, I did try the SRT 5x5x3 routine last week, I would have to do it with a clamp though, because I can hardly sustain an erection longer than a few seconds.
So I hear what you say that grow to inches more, it`ll be too much, but I dont think so. Time will show
