All were from rural areas of Missouri, Illinois, Oregon, Washington, or Idaho, places known for their “social conservatism and predominant white populations.” The sample skewed a bit on the older side, with 14 of the 19 men in their 50s or older, and most identified exclusively as exclusively or mostly straight, with a few responses along the lines of “Straight but bi, but more straight.” Silva sought to find out more about these men, so he recruited 19 from men-for-men casual-encounters boards on Craigslist and interviewed them, for about an hour and a half each, about their sexual habits, lives, and senses of identity.
Since this is a qualitative rather than a quantitative study, it’s important to recognize that the particular men recruited by Silva weren’t necessarily representative of, well, anything.
