The real sexual function of the frenulum is unclear. It has been associated with tissue delta. The tissue is observed to be very reactive and responsive to light and soft touches.
Researchers in sexual health, Crooks and Baur, described two extremely sensitive specific locations that many men find particularly responsive to stimulation are the corona and the frenulum.
This is noted to be “sources of distinct pleasure” and repeated stimulation of the structure can result in climax and ejaculation in some men.
The frenulum may be completely or partially removed during circumcision. The complete removal was reported to be between 20% and 33% of men, following the operation
Macht aber alles nix, denn:
Despite such statistics, the dampening of sensitivity in the penis is
thought to be negligible, as one third of the male population in the
world who had circumcision do not experience diminished sensitivity of
their manhood.
Ob solcher Logik rollen sich einen die Fussnägel auf...

Camille Paglia once commented: “Manhood coerced into sensitivity is no manhood at all.”
Hä? Geht es nicht eher um "Manhood coerced into insensitivity"?
