days off necessary?

I get pretty enthusiatic about hanging and jelqing, so enthusiastic that I find I don’t like to take time out (okay, I’m obessesive!)

Is it beneficial to growth to give the willy some time off? Or should I just stretch while the streching is good (and I’m single with the free time to do it)?

Listen to your body. The occasional rest day is beneficial, depending on your routine. If you intensely jelq, for example, perhaps every 3 days give your penis a rest. With hanging, your ligs will tell you.
