Tested twice, a few days apart, for about 12 hours each time.
Sorry, your approach isn't mine. I'll remain covered.
In practice, I retract my foreskin, and it can stay in place under the glans, without returning to its initial position.
In my experience, the contact of the glans with my clothing was unpleasant, but not painful.
At the end of the second attempt, a small swelling, smaller than a pea, appeared, and I managed to retract the foreskin back into its initial position.
For those who practice permanent foreskin retraction, aren't you concerned about the risk of paraphimosis?
