I'm seriously considering some sort of foreskin restoration, just reading some of the recent data and anecdotal stuff that's come out in recent years about being uncircumcised vs cut and what is lost during circumcision. I mean I still feel pleasure and everything but I still can't help but wonder how much improved it could be, to the point where it's starting to irk me. And again - at the risk of being too graphic I do have somewhat tight skin to the point where there can be some mild discomfort/tension when fully erect. Really tempted to at least try to obtain a mild form of restoration. Obviously I can't get back all that was lost but even if it's 40% that's good enough for me..
Putting skin on won't undo the anything.
With circumcision, the tip was cauterized (maybe that's not the right word, but basically the skin was raw before and therefore more sensitive, but it hardened after the skin was cut off).
Honestly, sex is good with or without circumcision. But it's best to be happy with what you have versus thinking the grass is greener.
