The Gay Americans by Anthony L. Stoner

Volume 2 focuses primarily on lesbianism; also, homosexual cunnilingus and fellatio versus heterosexual oral sex, sex toys, gay liberation, lesbian and gay pornography (some examples from Denmark, including a page from a Color Climax mail-order ad), etc. 'While the bookracks are sagging with works of scientific and clinical mumbo-jumbo, here at last is a compassionate book that treats our gay brothers and sisters not as 'Inverted Case Studies,' but as human beings.'
