Contraceptives might just beat out Lionel Richie as the hottest aphrodisiac. Keyword: might. The effects of Lionel Richie on lovemaking are yet to be completely quantified.
But according to a recent study by John Hopkins Bloomberg School of Public Health, couples who use contraceptives have sex more often. To draw this conclusion, researchers examined the answers of "210,000 sexually active women of childbearing age in 47 countries," in Demographic and Health Survey questionnaires completed since 2005. All these women were either married or living with someone.
The survey results showed 90% of women who use contraception admitted to having sex within the last four weeks. However, of those who don't use contraception, only 72% reported having sex (sad trombone sound effect) within the last four weeks.
