Reported sexual orientation doesn't match with sexual behavior

From EurekAlert:

PHILADELPHIA, September 19, 2006 – A survey of 4,193 men living in New York City conducted by the New York City Department of Health and Mental Hygiene found that nearly 10 percent of male participants who identified themselves as straight reported having sex with at least one man during the previous year.

Compared to men who identified themselves as gay, these men were more likely to belong to a minority racial or ethnic group, be foreign-born, have a lower educational level, and live outside Manhattan. Seventy percent reported being married. This group also was less likely to have been tested for HIV infection during the previous year and less likely to have used a condom during the last sexual encounter than men who identified themselves as gay.
