You may wish to reevaluate the importance of sex with multiple partners in light of the clear and extensive evidence that having many sexual partners is one of the stron­gest predictors of becoming infected with HIV, HSV, chlamydia, HPV, and numer­ous other sexually transmitted infections. You might also elect not to have sex with individuals who you know or suspect have had multiple partners. People with multiple partners probably know each partner less well and thus may be less successful in avoid­ing people who engage in high-risk behaviors.
