ABSTRACT
It has been recognized for a number of years now that, in the absence of a vaccine or cure for AIDS, efforts to contain the spread of the epidemic must be concentrated on bringing about widespread behavior change. Changing sexual practices, and particularly convincing people to use condoms every time they have intercourse, has become a central goal of AIDS prevention and education programs. Most programs have focused on bringing about individual behavior change. Sexual intercourse, however, is one of the most cooperative and social behaviors in our repertoire, and it crucially depends on communication between partners.
