A new research has indicated that good-looking and manlier men are better in bed and more likely to get their partners pregnant
Researchers from Pennsylvania State Universitystudied the intimate sex lives of 110 heterosexual couples. The men had their pictures taken and faces measured for symmetry and masculinity and participants answered a questionnaire about the timing of their orgasms and provided details of their sex lives.
Women reported experiencing orgasm more often during or after male orgasm when with 'high-quality' men, and reported experiencing orgasm more often before ejaculation - along with higher orgasm frequencies overall - when having sex with masculine and dominant men.
Sex Therapy New Zealand director Robyn Salisbury said that she was surprised by the findings, which ran the risk of affirming sexual myths and adding to the arrogance of good-looking people.
Salisbury said there were many factors in being good in bed including libido, mood and technical knowledge of the body.
"Looks might be a factor but I'm not convinced that it is a major factor. Those of us less good-looking shouldn''t despair," Stuff.co.nz quoted her as saying.
The study has been published in international science publication Elsevier's Evolution and Human Behaviour Journal.
