Men are more than twice as likely to continue dating a girlfriend who has cheated on them with another woman than one who has cheated with another man, says a new study.

Conversely, women are more likely to continue dating a man who has had a heterosexual affair than one who has had a homosexual affair. The study provides new insight into the psychological motivation behind men's desire for a variety of partners and women's desire for a committed partner, the journal Personality and Individual Differences reports.
