Uncut porn refers to all the penises that are showcased in this niche as being uncircumcised. A natural, intact male genital member has the presence of foreskin, known as the prepuce, around the glans (head). While circumcision has been a common practice in the United States for decades, regardless of religion, it is not performed (and sometimes frowned upon) in many parts of the world. Uncut sex videos celebrate the unaltered cock in all its glory.
