“Cuckolding routinely ranks among the top searches on the world’s biggest porn sites, as reported by neuroscientists Ogi Ogas and Sai Gaddam in their book “A Billion Wicked Thoughts,” for which they analyzed the contents of hundreds of millions of Internet searches. But as my own research has shown, reports of that sexual fantasy exhibit a surprising ideological pattern. For my book ‘Tell Me What You Want,’ I studied the sexual fantasies of 4,175 Americans from all 50 states. I asked my participants to report how often they fantasized about hundreds of different people, places and things — including cuckolding” researcher Justin Lehmiller writes in the Washington Post.

“A majority of heterosexual men (52 percent) said they had fantasized about watching their partner have sex with someone else. Heterosexual men who identified as Republican were the most likely to report having had a cuckolding fantasy at some point — and they fantasized about it more often than Democrats. Fewer than half of Democratic straight men (49 percent) reported having ever fantasized about cuckolding, and 19 percent said they fantasize about it often. By contrast, nearly two-thirds (64 percent) of heterosexual Republican men reported having had this fantasy, and 30 percent said it is a frequent fantasy. Republican men also reported more fantasies about infidelity, swinging and a wide range of sexually taboo activities, including voyeurism.”
