Methinks there's no harm in doing it daily, would only help in lightly stretching the chambers. But a daily routine, would it affect your potency during jelqing ? Somehow I'm of the view that you can have a finite number of erections per day & it gets used up every time (could be the nitric oxide levels or hormone levels or plain nervous insensitivity)... I've noticed that jelqing daily without breaks brings down my potency. This is for me, dunno about others. I don't know if its the case of overworking the penis, or the case of getting insensitive to daily dose of porn(while jelqing ).. What say guys?
