It seems like people have different experiences with cut frenulum. As I was circumcised as a full adult, having plenty of time to explore my frenulum before it was cut off, I can tell that for me frenulum removal made a big difference. As I knew that I will be circumcised some time in the future I tried to learn and remember how frenulum and foreskin felt. For example frenulum was sensitive enough place for me to reach an orgasm by just touching and rubbing it. And after frenulum removal (my frenulum was removed completely, sides of glans sewn back together) there just simply was no feeling. Completely numb. But I knew it already coming, so I wasn't neither surprised nor unhappy. I actually wanted it. I deliberately wanted to feel less in the area of ​​the fenulum.
