BACKGROUND Strict genetic monogamy leads to sexual harmony because any trait that decreases the fitness of one sex also decreases the fitness of the other. Any deviation from monogamy increases the potential for sexual conflict. Conflict is further enhanced by sperm competition, and given the ubiquity of this phenomenon, sexual conflict is rife. In support of theory, experimentally enforced mon...

A number of studies have found that involvement in concurrent sexual partnerships (sexual partnerships that overlap in time) increases sexually transmitted infection (STI) risk, and that such partnerships may be a major determinant of the rate of human immunodeficiency virus (HIV) spread. In the U.S., such partnerships may be relatively more common among African-Americans than among other racia...
