Welling LLM, Jones BC & DeBruine LM (2008). Sex drive is positively associated with women's preferences for sexual dimorphism in men's and women's faces. Human Behavior and Evolution Society in Kyoto University, Japan. June 2008.

Sex drive may be a generalized energizer of women’s sexual responses or may energize responses to potential mates only. Here we show that reported sex drive is positively associated with heterosexual women’s preferences for sexual dimorphism in both men’s and women’s faces (Studies 1 and 2). These findings for associations between reported sex drive and women’s preferences for sexual dimorphism implicate sex drive as a possible source of individual differences in women’s face preferences and present novel evidence that sex drive is a generalized energizer of women’s sexual behaviours and responses. Since masculinity is associated with both health and anti-social personality traits among men, increased attraction to masculine men when sex drive is high (and mating is therefore more likely to occur) may function to increase the possible benefits to women of their mate choices.
