Had circumcision done at a later age (62). Foreskin was removed and I love it although my tip gets somewhat numb. However, my frenulum was also removed, and I should not have had that done. It took away most of the sensitivity when having intercourse or when masturbating. The only sensitivity that is left is in the tip (glans) and it is extremely hard to get to a climax. Very frustrating because sometimes I just not get to that climax point.
My recommendation is to keep your frenulum intact if you have a circumcision done.
