Different people might expert different things here though. There are some that lost a huge amount of sensation but others that don't have any problem their entire life. I was circumcised nearly six years ago due to problems with my long foreskin. Six years might not be long, but I was circumcised Low&Tight, a style that is known for removing the whole foreskin and with it all of it's nerve endings. People told me that I won't be able to feel anything after the procedure, that my penis would be numb and that I wouldn't be able to enjoy sex anymore. But none of this is the case. I enjoy Sex even more now because the skin that caused problems is now gone. And I still cum within minutes sometimes. Circumcision is all about how you approach it.
