Youll gradually regain sensation in a week or two. Banding tight to cause nerve damage is fun play but I think your body builds resistance to it at a particular site.Im able to get numb enough to not cum for like 3 days, it used to be a month or two of waiting to have most back. I stopped though because there has been sluight loss of feeling (very slight i dont care really). Recently I tried banding and cooling, and that was a lot of fun. I found when your cock goes below 55F, you loose all feeling totally. It's hell warming back up if you do it quickly. I kept trying lower temps until I realized nothings going to hurt it unless it freezes. On one session I used plain ice water and according to the thermal camera reached 33.0F on my cock halves. I stayed down there for a while amazed by the lack of sensation. I took some time to stretch some scar tissue and put a few needles through my lifeless cock. I did not realise it but i spent almost 30 minutes under 40f and decided to unthaw when i noticed how much time passed. This time, the nerves waking up was not as bad...and they did not come back immediately upon warming. I began to worry my cock was dead but color and temp came back fine. I could cum but mainly from sensations in my subincision for about two weeks and nerve damage healed over 2 months. Might have been "frostnip" nerve damage.
