Hey mikeleebcfc, maybe check out information on this stuff too before you pick a course ..
'Dissolving' / healing the scar at rapidly-advanced rates using:
DMSO (Dimethyl Sulfoxide) mixed about 50/50 with distilled water or a 100% pure Aloe Vera juice. (The contents label should list Only aloe vera, or perhaps also water, but no extra fillers or substitutes.) --- And also possibly several drops of Iodine and/or high IU vitamin E.
-- So look up:
DMSO Scars
DMSO Aloe Vera
DMSO Iodine
DMSO Vitamin E
Iodine Scars
and anything else along the way that look interesting and authoritative. YouTube also used to have many great videos on its use both externally and internally, but they're in the middle of committing political (and then economic) suicide at the moment so there's no telling what all they have or haven't deleted / shadowbanned lately to protect their warped political views .. soooo, good luck there.
Anyway, .. Using the DMSO full-strength tends to cause uncomfortable itching. It effects increases in permeability of your cells .. and that raises their voltages into the range for healing (respiration, apoptosis)... so, if applied too strongly, an entire treated area might feel like a 'scab that's ready to fall off' ... Healing can = Itchy. The itchy reaction is kept down by weakening the DMSO with a diluent such as the water or aloe vera.
Some areas of skin are more prone to itching than others. The back of the neck is one of the worst areas. The penis isn't far behind. So try the 50/50 mix and if that seems itchy then you can mix in a bit more diluent for the next time.
While they're being mixed together, the solution will warm-up briefly as it 'binds'. When it cools off it's ready to use, and its shelf-life is essentially forever.
Only mix and store in glass containers, such as a smaller mason jar etc. You'll run into plenty of info on this while checking into it.
The solution will absorb through/into your skin very quickly. Any remaining on the outside of the skin after 10 or 15 minutes isn't going to add anything extra and can be wiped off.

aaaaand ... A decent book on it .. because the Establishment hates this stuff and has websites devoted to spreading FUD. --- The reviews and tips for that book will provide some insights

People also (I do) take the Iodine and DMSO internally. 2 Drops of the 5% Iodine mixed with water, daily, ... and the DMSO isn't a critical dosage level (it has the same toxicity inside the body as Water, ie .. none) so just a little 'bloop' of it into a glass of water, not quite a tablespoon. Mix and let sit for 3 minutes to bind before drinking. It has a taste. Some people prefer mixing with a juice, like orange juice, for taste. I just do it raw.
These two are great internally for health whether or not you choose to use them on your dick.
I used to do a lot of rock climbing (and boulder running) years back. Never with a rope or gear, besides 'EBs'. Nearly died several times .. but never tore my dick open, you've definitely got me beat there. Ouch!!
Best of luck!
I'm sure there are research notes related to both, I'd consider searching those and studying, then making the choice. Of course the doctor(s) should know the best route, but there's agendas and whatnot, so it's good to study by yourself as well.
