Almost 10% of men who said they were straight had had sex with at least one man during the last twelve months, according to a new study carried out by the New York City Department of Health and Mental Hygiene. 70% of them were married. Many of these men said they had not used a condom and had not been tested for HIV.

In fact, the researchers found that straight men who had had sex with another man during the previous year were less likely to use a condom than gay men who had had sex with another man during the previous year.

A large proportion of the straight men who had had sex with another man were either of low economic or educational status, were foreign born and lived outside the Manhattan area.

The researchers were surprised that so many married straight men admitted to having sex with another man.

The researchers said it may be necessary for doctors not only to ask a patient whether he is heterosexual, gay, or married, but also what his sexual practices are, when assessing for risk of sexually transmitted infections. Public health prevention messages should target risky sexual activities, rather than be aimed exclusively at gay men.
