I'm circumsized, everything works (very well!) and am not unhappy with it. However, I do wish I hadn't been cut or at least I'd been given the option at a later date. So have been restoring my foreskin lately...and the increased sensitivity and skin-looseness already gained has sealed and confirmed my decision to continue.
I promise not to write anymore...have done so in numerous similar threads and the reasons to/not-to cut end up leading to arguments that sound almost religious in their righteous indignation. I'm glad we're all trying to be a bit more civil this time.
And just so you know: I like cut AND uncut cock. I think of myself as a Switzerland-like Penis Ambassador!
