When it comes to men making decisions on condom use for casual sex, there may not be more to it than meets the eye. In a survey of 51 heterosexual men between the ages of 19 and 61 published in BMJ Open, researchers found that men’s intentions to use a condom during casual sex varied based on the perceived attractiveness of their potential partner. Specifically, the more attractive a woman seemed to each participant, the lower their intention to use a condom during sex—even if the woman seemed to have a relatively higher risk of having a sexually transmitted infection. Though the study was small, the finding backs up several others that have found that perceived hotness of a potential sex partner is a key determinant in people’s decisions on whether to have sex and have safe sex (for men and women). http://arstechnica.com/science/2016...safe-sex-depends-on-how-hot-their-partner-is/
