I do this regularly now but with a twist.
Day 1: Clamp/pump
Day 2: stretch
Day 3: clamp/pump
Day 4: stretch
etc etc etc
For Clamping it’s 1/1, for stretching it’s 1/1.
I normally pump in morning and wear a cock ring during the day while at work then when I get home I clamp for anywhere between 5min to one hour at a time depending on how my penis feels.
Obviously, nobody here is going to recommend my routine for someone just beginning. All I can say is try 1/1 for a month or two and see how you go. If your experiences are good, stick with it, if not, try a different roster.
Just my 2 cents.
Nobody, and I strongly believe NOBODY can give you a definite answer for the perfect routine/roster for PE.
It’s all personal experience.
