Multiple sex partners (MSP) is the measure and incidence of engaging in sexual activities with two or more people within a specific time period.
[1] Young people having MSP in the last year is an indicator used by the Centers for Disease Control and Prevention (CDC) in evaluating risky sexual behavior in adolescents and a tool in the monitoring of changes in HIV/AIDS infection rates and deaths worldwide.
[2] Epidemiologists and clinicians who quantify risks associated with MSP do so to identify those who have had sexual intercourse with more than one partner in the past 12 months.
For the purposes of the World Health Organization (WHO)'s effort to eliminate HIV infection, quantifying measures progress in reducing the percentage of those with AIDS.
WHO recommends that additional indicators that quantify MSP more precisely to capture the reduction in multiple sexual partners in general.
[7] A social history (abbreviated "SocHx") that part of a medical exam addressing familial, occupational, and recreational aspects of the patient's personal life that have the potential to be clinically important.
Promiscuity can mean that a moral judgement is made because some parts of societies promote sexual activity to occur only within exclusive, single-partner, committed relationships.
[11] The likelihood of developing substance abuse or dependence increases linearly with the number of sex partners, an effect more pronounced for women.
