Don't worry eventual it will be desensitized taking a lot of the pleasure out of sex.
Why on earth as one circumsized (at birth) to another circumsized peron did you do this to yourself?
Im with serious sam, it will desensitise eventually, remember the head is full of nerve endings its not like cutting your finger. but please tell me and the wider uncut community why you felt the need to cut off somthing you were born with?
