Let me see, 5 minutes at 3”hg and you already think pumping is not for you. I don’t even think you have started pumping yet and are not even close to becoming conditioned to a brand new experience for your cock. Pumping is not something to fear, it is something to enjoy. It feels good and looks good. I think it is best to start aroused and end aroused.
I watch porn when I pump. I enter the tube with an erection and after my session I put on an elastic cock ring to maintain my post pump size and continue with either edging or masturbating for 5 to 10 minutes.
5 minutes isn’t going to do anything as far as making improvements goes. It is also not going to hurt you especially at only 3”hg. To start making lasting results you have to eventually work up to 15, then 20, 25 and then 30 minute continuous sessions.
So to start, go for two 5 minute sessions at 3”hg. Start with an erection and try to maintain your erection with massage during a short break between sets. End the pump session with further edging or masturbating to enjoy your post pump results that at this point will not be very impressive if anything at all. At this conditioning stage I would say pump 2 or 3 days on and 1 day off.
After a couple of days increase by pumping for 10 minutes straight @ 3”hg. Then after a couple of more days go for 15 minutes continuous @ 3”hg. After getting used to that, start your 15 minute sessions by spending half the time @ 3”hg and the remainder @ 4”hg. After you get used to that, make your next increase to your 15 minute sessions by spending the first 5 minutes @ 3”hg, the next 5 @ 4”hg and the last 5 @ 5”hg. Now you are getting into the fully conditioned stage. The thing that remains the same for all pump workouts is start with an erection and end with an erection.
After all of this, you can begin getting into true size increases by working up to the before mentioned continuous session times of 20 then 25 and eventually 30 minutes. Keep 5”hg your max pressure for the first couple of months and by then, you will know enough about pumping to start exploring higher pressures and your own routine style.
