Well...first I'm gonna cop a guilty plea to being a really lazy and inconsistent "Penis Enlargement'er", and I rarely measure at all. Having said that, though, I'll say that with my actual dedicated girth work, I've probably gained 1.25"-1.5" in both length and girth.
When I finally did decide to measure, after about a year or so of on & off Penis Enlargement, I could get about 7 inches length on a good, hard, full erection day and a reliable and not difficult at all 6 inch girth.
With that size, I've "bottomed out" on my Ol' Lady many a time, which she didn't really enjoy all that much...but the girth...oh yeah, she really got off on the girth. Luckily, with the stretching method I described girth gains come rather easily; after a stretching session; girth work, ain't actually much work.
One of the best things I've discovered about this method is that, not only do you practice stretching from just about any angle you can think of, but you also train for girth in the same 360 degree environment.
If I was a more consistent Penis Enlargement guy I know damn well I'd have hit the ol' 8x6 a while ago...maybe more.
Hope this yields the results yer lookin' for; good luck.
