Lately I've been doing a different routine. One thing I learned at [words=http://www.mattersofsize.com/join-now.html]MOS[/words] is to always increase the intensity to the max my cock can handle.
I've been doing at many sets of slow squash jelqs (with my own modification for length work too), squeezes, and 110% jelqs (jelqs that start with an intense squeeze that gets me to 110%). Combining that with far less frequent masturbation (I only cum twice a week now, and I used to cum every day), I have gained a lot of girth recently. My GF said that I went from being "thick to super thick", and now I stay hard for far longer without trying and precum much more.
