Circumcision splits along national lines: most American men have had it done, while most British men have not, and this film asks which side has it right. Doctors, sexual health researchers, and circumcised and uncircumcised men themselves weigh in on whether removing the foreskin changes sensation, hygiene, or risk of disease, and whether partners notice a difference in bed. The film treats circumcision as a live medical and cultural argument rather than a settled fact, setting American parents who circumcise as routine against British parents who increasingly do not, and letting each side's reasoning stand on its own. Interviews range from clinical explanations of nerve density and infection rates to blunt personal testimony about sex and self-image. It stays a frank, adult conversation about a body part most documentaries avoid discussing directly, without turning into anything sexually explicit.
