uc | the status of a person's penis, in that it is uncircumcised
Meaning
Originally, circumcision was required, according to some religious beliefs, and was later done for supposed medical reasons.
Today, those 'medical' reasons are suspect, or simply not believed to be valid.
Those who prefer uncut dicks, or have an uncut penis, claim the head is far more sensitive, allowing for a more intense orgasm, or feeling during intercourse, or masturbation.
