According to a recent study by David Ley, Justin Lehmiller and the writer Dan Savage, acting on cuckolding fantasies can be a largely positive experience for many couples, and hardly a sign of weakness. Today, cuckolding has become fetishized into a powerful sexual fantasy for some men, who get aroused by the idea of their romantic partner engaging in sexual activity with someone else. Women also share this fantasy, but less so than men.
"This fantasy has been around as long as marriage and sexuality," said Ley, whose book "Insatiable Wives" addresses cuckolding in heterosexual couples. "But we're hearing more and more about it these days, and more people are rejecting the social stigma against this fantasy."
Lehmiller surveyed thousands of Americans and found that 58% of men and about a third of women had fantasized about cuckolding.
"Overall, our research found that for the most part, cuckolding tends to be a positive fantasy and behavior," said Ley. "It doesn't appear to be evidence of disturbance, of an unhealthy relationship, or of disregard for one's partner." But there's an important caveat, added Lehmiller. "We found several personality factors that predict more positive experiences acting on cuckolding fantasies. For those who have a lot of relationship anxiety or abandonment issues, who lack intimacy and communication, and who aren't careful, detail-oriented planners, acting on a consensual non-monogamy fantasy could very well be a negative experience," he said. "In other words, not everyone who has a cuckolding fantasy should think about acting on it."
