Every guy on the go needs a Little Black Book, and one of the best comes courtesy of Queer Corps, the gay youth division of Boston’s venerable AIDS Action Committee. Designed by Derek Cash, 25, and a crew of volunteers jazzed by the freebie put out by Seattle’s Gay City Health Project, this gay scout manual has the newest skinny on everything from STDs and condoms to street drug/protease interactions and negotiated safety. Write to AIDS Action at 131 Clarendon St., Boston, MA 02116, or e-mail queercorps@aac.org.
