In 2015, a team of researchers primarily based out of the Center for Sexual Health Promotion at the University of Indiana surveyed 2,021 American adults about their sexual behaviors. Participants completed an extensive, fifteen-minute questionnaire in the comfort of their own homes under total anonymity. Their responses, made public recently in the journal PLoS ONE, reveal the sexual behaviors and preferences of American adults in greater detail than ever before.
