When I was cut, it was way too tight. There wasn't enough left for a full erection. Erections were painful, and there even was tearing! Not knowing any better, I assumed it was the same for every guy, and wondered why sex seemed so popular, when it hurt so much.
Then I saw one of the guys in the house behind mine. He wasn't hard, just didn't want to bother going back to the house to urinate. He flopped out his penis, and it didn't look like mine. Before he started the flow, he pulled the skin back, and I wondered how he could do that, because it looked more like mine, but with something extra.
Eventually, I found out what had happened, and was horrified that someone would do such a thing. Learning about restoration made me want to do something about it. Months of work eventually rewarded me with erections that didn't hurt, but by that time, I found out there were other things I was missing. Partial coverage brought increased sensitivity, and other sensations that were unexpected.
Those of you who have full coverage, just think about the sensations you feel if you urinate without pulling things back. Go a step further, and let the urine inflate your foreskin (perhaps something for when you are showering).
Now think about another part of you that is usually moist and has covers, your eyeball. Do you think you could stand having your underwear rubbing against your eye all day long? Wouldn't you want to do something about it, once you learned it wasn't the way things were supposed to be? Would you not get upset at someone who forced that torture on you?
I have occasionally had someone share the warmth of their foreskin with me, and am now much better prepared to enjoy it to its full extent. I just wish I could do it more often.
