Researchers have discovered that men are less likely to practice safe-sex if their partner is more attractive. The study also revealed that men are more attracted to women they deemed “risky” (in other words, women who were most likely to have STIs). The researchers stated,  “Men who are more attracted to ‘riskier’ women are just as disinclined to wear a condom when they have sex with these women as men who are more attracted to ‘safer’ women.”
