Fay, Robert E.; Turner, Charles E.; Klassen, Albert D.; and Gagnon, John H., "Prevalence and Patterns of Same-Gender Sexual Contact Among Men," Science, 243 (January 20, 1989), 338-348.

Abstract:

Using data from 1970 and 1988 surveys, it is found that never-married men are more likely than other men to have had a same-gender sexual contact within the last year, but approximately half of the men estimated to have such contact are found among the more numerous population of currently or previously married men.
