I've had the cut, not regrets. I'm not into dicks, but kind of prefer the appearance. Some foreskins have a lot of loose skin and remind me a bit of an elephants trunk

But having said that, there are also some unfortunate hack jobs on circumcisions. But it really wouldn't bother me if I was uncut either, not these days anyway. Given the choice, I'd still prefer to be cut though.
Back in my school days the majority were also cut, so the few boys with foreskins kind of stood out in the changerooms, so maybe back then it would have mattered as I had enough problems fitting in as it was, so I would have been self conscious about it.
Funny thing, I was completely unaware about cut/uncut back then as a kid, didn't realise I was born with extra skin and it had been cut off. I just put it down to some dicks looked different than others

I often read that guys who are cut have less sensitivity. I don't know what it's like to be uncut, but my dick is incredibly sensitive, especially the head. I've had to ask my girlfriends over the years to go steady with oral or caressing during foreplay, or we risk not making it to the main event. I even precum little sometimes with underwear rubbing

So no lack of sensitivity here, if anything, too sensitive!
