Ask your dick.
IOW, let the condition of your penis relative to the ex’s your doing determine your frequency. Don’t PE if your’re shriveled and overworked. Instead, give it a break or do PC work until you get back to a nice, fat hang. With manual exercises there is likely to be some collateral damage to the vascular system within the penis, some exercises more than others will contribute to this situation and it’s probably due to the individual and their technique. I believe the tissues which play the most signicicant role in PE results are also the toughest. A paradox in that the weaker tissues more susceptible to overstress and injury are not really the ones which have such a great effect on size. It may be everday you can do this, every other, perhaps a different scenario altogether. Best and safest for you to find out for yourself by mild experimentation at first. The small amount of gain that I achieved came during a period or “erratic PE” where the sessions where not on a rigid schedule and plenty of off days were inadvertanly involved. Whenever my next attempt takes place, it will follow the rule of appropriateness…relaxed, fat hang with maximal erection potential. No PE on swelled dick. For me, it’s just fluid build-up and does not contribute to anything but an overstressed cock. Schedule on paper be damned, go by the condition of your organ. Good luck. Groa
