Hey, brother.
What do you mean by foreskin stretching?
At medium tension (6-900 grams of force) I can wear my penimaster up towards 4-6 hours without taking a break. I used a kitchen scale to double-check the tension. On my device, 900 grams is at three visible lines, counting the one at the very bottom / base of the device.
Important! I don’t recommend going straight for such long sessions. Instead, do increases of 15-20 minutes per session over weeks to be sure you do not hurt yourself: 1.5 hours, 2 hours, 2h 15m and so forth. Remember: 3 hours is the recommended maximum session length by the supplier.
I did have pain in the beginning of my journey. My solution was to experiment with the different sluice and diaphragm sizes until I found the most comfortable combination for me. This took time for me (months, and I am still experimenting).
Turns out the medium sluice was too tight for me. After I started wearing blue (large) sluice and diaphragm my pain is almost completely gone.
In addition, the tension I used was also too high because the springs had more tension than the user manual indicated. I were using 11-1200 grams of tension, but I believed that I were using 900 grams.
I also recommend that you use as little vacuum as possible. Experiment to figure out how little vacuum you can use and still get a positive lock with the whole glans inside the chamber.
I still get pain sometimes, below the glans. I suspect it is when I use too much vacuum or enter the chamber at an awkward angle.
Two other tips:
1) If you have blistering problems (I had this), try wrapping the glans with micropore tape that breathes. I have not had a blister since I implemented this. I wrap the whole glans completely with one layer of this tape. Only area not covered is the urethra. I do this by engorging the glans, then applying the tape. Then I let the glans return to normal flaccid size before I enter the chamber. Rather than letting the vacuum draw me in, I gently push with it. This allows me to use less vacuum.
2) I also use soft medical pads below the base of the unit where it meets the scrotum to prevent contact burn during longer sessions. This has pretty much removed any contact pain for me.
