Well said, Dickstrong. To build on what you said, what you want to try to do is work up to applying just enough force or stress to promote growth without making your penis stronger and tougher, and more resistant to stress. This is where a workout even less stressful than the Newbie Routine may be a good idea.
OneNightStand, you can always increase your efforts later on. In the early days of PE, you are learning the exercises and conditioning your penis to taking a little more stress (and a little different kind of stress) than it has been used to. And I think it’s safe to say that PE is a different kind of stress than your penis is used to; else you would be gaining size from masturbation or intercourse.
For that same reason, I’d suggest dropping the O-bends for now. Save those for later.
Feeling stressed or fatigued may let you know that you’ve done too much, but not feeling that way does not mean that you have not done enough, if you follow me, so don’t let that worry you.
