I can see thebeneficience of erect stretches provided you can get a good grip on your penis. However, I’ve had penile anatomy on the mind lately and I do believe that erect stretches (all stretches in fact) are probably best if targeted on the upper portion of the penis.
If you pull straight up you place more stretch on the CS and its attendant connective tissues as opposed to the CC and it’s attendant tissues. I have a feeling that erect stretches may very well target the main lig where it hooks into the body. The CC, I believe, is what lends rigidity to the penis. It’s the part that gets truly hard and is able to take advantage of the erect stretch by transferring a large percentage of the stress to the actual ligament. Pulling up reduces this a bit. Pulling down would stress it more. Plus, when you pull up, the penis is much more likely to “pull back” through involuntary contractions of the PC or some attendant muscles.
Of course, there is also the consideration of which way you want your penis to point while erect. I don’t know about you folks, but I would like mine to stick straight out or even slightly upward. If we stretch the abovementioned ligament too much it may become so limber that it doesn’t “stand up” any longer, but just kind of hangs there half-heartedly even at full mast. That’s the porn star look I know… but it’s somewhat inefficient for actual sex I think. The angle of the penis is somewhat important I feel.
Curious. Curious.
Then again, this is all conjecture and opinion. Some people want the drooping pornstar look. Pulling down may transfer less force into the penis despite my rationale because you are able to generate more force by virute of a better grip as mentioned above.
As soon as I completely heal my unit I’m going to get a cock ring and do a bit of (Careful!) erect stretching and feel where it hits and all. Until then, I have no way to experiment.
