Italy's extramarital sex has risen sharply in recent years to hit one in two couples and 7% cheat with gays or lesbians, a survey said Thursday.
''Cheating has seen a considerable increase in the last few years and the phenomenon of homosexual cheating has emerged,'' said Gian Ettore Gassani of the Italian Association of Marriage Doctors (AMI).
''Ever more often, in lawsuits for marital infedility, it comes out that the other person is of the same sex as the cheat,'' he said.
Women are catching up with women in straying from the marital bed, accounting for 45% of cases.
About 60% of cheating goes on with work mates while some 40% of cheats hook up with someone outside work or online, AMI said.
