Girth can be very elusive, even after many years of work. For some guys, myself included, it can be very frustrating and seem hopeless at times. During my first year I made quick and decent girth gains but soon I hit a plateau and I was starting to become reserved to the thought that I may have tapped out. When I thought I was tapped out I was around 5.5" of girth and since that time I have added over 1 more inch. My first year was really spent doing wet jelqs with some, but very little, work in other girth exercises. Those who have access to the pay site can see my progression as the PHASES are the exact path I followed (routine wise) I think I spent a total of around 7 month in a dead freeze as far as girth is concerned and I knew something had to change if I was going to make any additional gains. What worked for me was a more demanding girth routine. I started doing super sets with Double Forced Jelq and Bend and Isolated Compression Squeezes and I would finish my routine with Toilet Compression Squeezes. This did the trick and the reason why is the principle I have followed ever since; MAXIMUM EXPANSION. Maximum Expansion, for me, means getting myself beyond my normal engorgement by at least 10%: (measure girth pre-session with full erection x .10 + Normal Girth = Goal at end of session) So if your girth is at 6.5" normally you will want to shoot in the neighborhood of 7" of girth after your session. This sounds easier than it is and there are time I just can't do this but the point is to try. You will not be able to do it every session but for the most part you will.
Doing this forces girth gains as it pushes your normal engorgement past normal levels deforming and demanding it to hold more blood. Any girth routine will have it's limits and when these limits are reached a new girth routine will be necessary to continue growth. I am not saying people should drop a routine every other week but it is important to watch your routines very closely to measure the success you are having and know when to change shit up. For me it has only been 5 times throughout my entire time doing Penis Enlargement (hence the 5 Phases) but a complete routine change is not always the answer either. There were many time I stuck with my existing routine only changing the intensity and total reps, this would suffice but when it didn't a total change was critical.
As Shafty mentioned, VIAGRA is a big help, especially when girth routines become demanding. It is nothing to feel bad about, I simply see it as my own personal Penis Enlargement Pill. It costs me about $1 per day to use and the results are amazing.
Today my routine, and for the past 6 months, has been Slow Squash Jelqs and for the first time I can say I really do not see a ceiling on the potential of this exercise...but I am sure it will come and when it does I will be ready with a new Girth exercise.
