Men, most of them naked, talk about their penises. The men range from 17 to 70+, all are from the U.S. of diverse races. Several are artists or performers. Some are gay, others straight; two are transgender. One is paralyzed below the chest. The interviews are edited around themes: discovery, early sexual experiences, masturbation, size, oral sex, libido, performance, disease and maladies, maturity. A lexicographer discusses language, especially slang; a few archival educational-film clips divide the topics. Images and stories mix with facts and philosophical reflection. The usually private becomes public.—<[email protected]>
