Sorry to take so long responding!

I used a variety of methods over the years, starting with manual stretching and T-tape, which I'm not super fond of but might have helped in the beginning before I had much to work with. Luckily my circumcision was not super tight originally. Later on I tried various devices that hold and stretch the skin with a silicone cap over a rounded elongated piece that sits against the glans and later, ones that inflate the skin with air while its stretched over a similar device. I also used these silicone "cupping" devices to suck and stretch the foreskin down this ~3 conical tube, and secured the suction with silicone finger sleeves stretched over the tube onto the skin of the shaft - I haven't seen anyone else mention this method and found it very helpful.

As the foreskin grew more I found different manual stretching techniques to be more effective and I mainly use those now. I experimented with modified adhesive pads on a TENS device to strengthen the loop of muscle at the edge of the foreskin to ensure more secure coverage, which may or may not have helped but was, uhh, interesting I guess? Also icing the pulled forward foreskin after a hot shower also encouraged tightening at the front end for a more natural constriction and retention during my day.

I intend to continue stretching for a while yet until I'm satisfied with it, and able to have full erect coverage, t pulls about halfway up the glans now when fully erect. I haven't had any ill effects or injury apart from the occasional mild scuffing, had been haphazardly attempting to restore for about 2 decades but only really began in earnest during the pandemic when I needed a hobby.

Thanks for asking!

Oh no offense taken, to each their own. I just didn't want casual readers to think the process is harder than it actually is or that it doesn't produce worthwhile results. I'm as surprised as anyone, who'd have thought something like that could be somewhat reversed!
