The term "promiscuity" is not a medical definition, it is a value-loaded opinion. I don't believe that it has any use in health care circles. Its important to be specific - is the person having sexual relations with multiple partners, is the person a sex worker, is the person engaged in serial monogamy? Some cultures define "promiscuity" as dating more than one person even though intercourse never occurs. The pope is wrong. The use of condoms has decreased the spread of HIV/AIDs. Do people engage in more and different sexual relationships as a result of condoms? Research from the 70's said "no".
