Human sexual promiscuity is the practice of having many different sexual partners.^[1] The results or costs associated with these behaviors are the effects of human sexual promiscuity.

A high number of sexual partners in a person's life usually means they are at a higher risk of sexually transmitted infections and life-threatening cancers.^[2]

Research has also shown that there might be some benefit regarding the health fitness of the offsprings of promiscuous females in some animals.^[3]

Having multiple sexual partners is linked with risks such as maternal deaths and complications, cancers, sexually transmitted infections, alcohol, and substance use, and social condemnation in some societies.^{[2][better source needed]} A higher number of sexual partners poses a greater risk of contracting sexually transmitted infections, mental health issues, and alcohol/substance use.^[2]

Promiscuity in adults has detrimental effects on physical health. As the number of sexual partners a person has in his or her lifetime increases, the higher the risk he or she contracts sexually transmitted infections.^[2] Promiscuous individuals may also be at a higher risk of developing prostate cancer, cervical cancer, and oral cancer as a result of having multiple sexual partners, and combined with other risky acts such as smoking, and substance use, promiscuity can also lead to heart disease.^[2]

Studies have also shown that individuals who engage in long-term relationships, as opposed to hypersexual and promiscuous behavior are less likely to fall victim to domestic violence.^[2]

Some research finds a correlation between mental health risk and multiple sexual partners.^[4]
