Most British guys I know are uncut. Although I have no issues with guys who have it cut for personal preference - I don’t think it’s medically necessary at all. If your foreskin is tight then you can get a procedure called frenuloplasty, which is done to extend your frenulum and still keep the foreskin intact.
Some guys, especially Afro-Caribbean, get it cut for the prevention of Aids etc. Again I see no evidence of this at all. If the foreskin is the issue, then surely pulling it back and dabbing some water on it should keep it hygiene.
Having your dick cut should be the last resort after everything else is done. The sensitivity your foreskin gives when running against the head is simply priceless. My advice is to think 3 times before you cut that fella.
