I might be a bit different as I have taken only 1 day completely off from clamping last 16 days. But some days, I have only clamped one time in 10 minutes, some days 5 times and a couple of times with two clamps. I feel no problems with stimuli, no problem to get erect again for another set of clamping and actually enjoy the feeling of have a clamp on. Tomorrow, I will take a day off as I will do 5 sets today and probably have sex tonight (cannot imagine it will by of any problem). I am a newbie in clamping (tried cable ties a couple of months back) and thought this would be worse than it is. Stretching was for me worse with red dots, pain in the root etc.
I do not recommend any of this and I understand that I heal faster than most people…or perhaps do not clamp off enough ;) (I am sure I do, discolour and everything). But I have made my penis used to pretty rough exercises during my stretching period, really hard v-stretches, so it is perhaps used to tough treatment. I doubt that taking more days off would help my progress but perhaps I am wrong. I will try another way with more days off for October to see if there is any differences.
