Why I Lost Sensitivity In Frenulum?

I my self cut of frenulum on penis with no problems, i used nail serzers and cut it of 2 times with some bleeding and healed up fine. I did it because i wanted my foreskin to stay back because the frenulum keeps it forward, but when it was done it still stay forward, there was no diference at all. I am glad i did it, now i can masterbate behind the gland and have no pain and soreness from the gland.I find the frenulum serves no purposes besides being the most sensitive part of the penis.
