There’s too much information regarding FR (foreskin restoration) techniques and issues to post in this forum. Do a Google search and you’ll find a variety of sites dedicated or related to the practice. A good place to start is the web site of the National Organization of Restoring Men (norm.org).
Restoring techniques include the use of medical tapes (T-tapes, J-tapes, Pill tube, crossed tapes, etc), home-made and commercially available tapeless devices (TugAhoy, TLC, DTR, CAT II Q, and others), or even manual tugging. Most beginners are best suited to starting with some sort of tape based technique due to a lack of available slack shaft skin. Tape based methods typically are more comfortable for extended wear, but tapeless devices offer convenience. If you decide to try tapeless, I’d suggest you look carefully at the TLC. It’s cost is relatively modest, and it comes with a 30-day money-back guarantee.
There’s no hard and fast rule as to how long it would take to finish a restoration, but it would appear from numerous postings on FR-related boards that finishing in two years would be wonderfully fast. Many are at it for twice that long or more. There is no clear understanding about what precisely is happening with restoration, but there’s a shit-load of armchair speculation—each one of us is sort of reinventing the wheel. In two years of T-taping I gained a modest quantity of new skin (roughly one inch, possibly more), which is depressingly slow progress. I’d need at least three times that to get coverage. After a long break I’m back at it using a home made tugger. I bought a TugAhoy several years ago, but could not tolerate it due to pinching and a bad reaction of my glans to the latex coating on the inner shell. I have recently tried the DTR and CAT II Q, both well made tools and fairly priced considering their construction. Both however do cause me acute pain from pinching, so I’ve resorted to a self-made tugger which I can wear a bit longer before having to remove due to discomfort. Going back to tapes isn’t much of an option for me because of PE and other factors. Note that many guys can wear tapeless tuggers just fine—I seem to be cursed with them.
Finding a technique that is comfortable is critical to FR. You’d be at this for at least two years, most likely, so persistence is essential. Comfortable wear makes the persistence much easier. I try to tug for at least 10 hours daily (at quite low tension due to my own comfort issues), with nights off. No one knows with certainty whether part-time or full-time tugging is best. When T-taping I maintained nearly a 24/7 routine, but my results were meager. Now I am doing part-time as an experiment to see if it works better for me.
You don’t mention in your post whether you practice PE, but since you’re at Thunder’s I’ll assume you do. Consider that FR is similar to PE in that it is a long term effort. Time spent tugging is what gets the job done, so you want to make your tugging a part of your regular daily routine. Some accommodation will have to made in lifestyle as most of us want to keep our FR efforts discrete. If you’ve got a spouse or partner it may be best to get things out in the open rather than try to hide your tugging, only to end up in an embarrassing situation.
Understand too, that like PE, common sense and moderation in FR will keep you out of trouble. Avoid the temptation to get aggressive with tugging tension levels. Penile skin is delicate and complex. There’s no reason to do any more damage than was already done during your circumcision. Pay close attention to what you’re feeling when tugging. Any pain or discomfort means you need to stop and figure out what is the cause, then make any required adjustment in your tugging method. Ideally, you don’t feel much of anything during your daily tugging, except perhaps a mild tugging sensation. Once you find that “sweet spot”, then let time do the work for you.
