Can you tell if a woman is a lesbian just by looking at her face?
ereas previous work has shown that male sexual orientation can be accurately and rapidly perceived from the human face and its individual features, no study has examined the judgment of female sexual orientation.

Do people naturally turn their head to the right when kissing?
ssing behaviour was observed between kissing couples: about 80% turned their heads to the right to kiss. To remove the influence of one kissing partner upon the other, kissing behaviour was also observed between participants and a symmetrical doll's face: about 77% turned their heads to the right to kiss. There was no significant difference in handedness between right- and left-kissers: both groups were predominantly right-kissers. It is thought that motor bias rather than emotive bias influences kissing behaviour. Source:…

Is a roller coaster and a Red Bull a smart first date?
ything that gets us amped up and excited can make us more aroused: Heightened states of generalized CNS arousal are proposed here to facilitate sexual arousal in both males and females. Genetic, pharmacologic and biophysical mechanisms by which this happens are reviewed. Moreover, stimulation of the genital epithelia, as triggers of sex behavior, is hypothesized to lead to a greater generalized arousal in a manner that intensifies sexual motivation. Finally, launched from histochemical studies intended to characterize cells in the…

ructural equation modelling was used to assess the strengths of the links between sexual satisfaction and self-reported (a) relationship well-being, (b) mental health, and (c) physical health for women in same-sex (i.e., homosexual, n = 114) versus mixed-sex (i.e., heterosexual, n = 208) relationships. Participants came from a large-scale Internet study. Sexual satisfaction was found to be an extremely strong predictor of relational well-being, a strong predictor of mental health, and a weak to moderately strong predictor of physical health.…
