Its probably best to jelq at an angle where you can keep a good even pressure throughout the stroke. This might have a lot to do with keeping a good quality erection which will relate to the general looseness of the ligaments and consequent erection angle.
>How long should a beginner routine last : a month or two before moving on to more advanced exercise?<
At least 2 months I think. You’ll notice a change in the penis within that time, it will gain more resilience to pressure and look a great deal more veiny. When you start doing the squeezes its easy to rush in and cause injury (I did this myself) so start carefully.
Jelqing is a primary exercise though its not something that should be seen as a beginners exercise, you’ll just get better at it as time passes and be able to add little tweaks to make it more and more effective.
Luvdadus still does the newbie routine.
