If you suspect your husband or partner is cheating on you during his trip to Thailand, you’re not alone. As a seasoned detective agency, we have caught hundreds of foreign men engaging in infidelity in Thailand, time and time again. We’ve worked on cases involving men from all walks of life—young, old, married for decades or just a few months—and the patterns we’ve uncovered are shockingly similar.
Thailand, with its infamous nightlife and sex industry, is a notorious hotspot for men seeking extramarital affairs. With over 150,000 sex workers estimated to be working in the country, according to UNAIDS, the temptation is all too real for many. Based on our investigations, the number of men who cheat during their visits to Thailand is staggeringly high, and the consequences for their relationships back home are often devastating.
Our detectives have worked on hundreds of infidelity cases in Thailand, and the sad reality is that foreign men engaging with sex workers here is incredibly common. Men travel from their home countries to Thailand under the guise of “business trips” or “holidays in the sun,” but many have ulterior motives. The bars, go-go clubs, and massage parlours of cities like Pattaya, Bangkok, and Phuket are filled with foreign men seeking sexual services. We’ve caught men ranging from their twenties to their eighties—no age group or type of relationship is immune.

Through surveillance, we’ve captured undeniable evidence of infidelity: men spending time with prostitutes, ladyboys, and even multiple partners during the same trip. These men rarely match a single stereotype—some are white-collar professionals, others are retirees, and many are family men. But one thing unites them: they believe they can get away with it. With alcohol, nightlife, and a sense of anonymity on their side, many feel emboldened to indulge in risky behaviours they would never consider back home.
Most men engaging in infidelity while in Thailand do so in obvious venues like beer bars, go-go clubs, or massage parlours. According to UNAIDS, Thailand's sex industry is widespread, contributing to over 3 million visits to sex workers annually. While men might claim they’re “just having a beer” or “playing golf,” the reality is that many of these bars are staffed with prostitutes. The “bar fine” system—where a customer pays a fee to take a bar girl out for the night—is incredibly common.
Beyond the bars, nightclubs are another hotspot for infidelity, where ‘freelancers’—prostitutes who operate independently—often approach foreign men. Our detectives have seen cases where men hire sex workers under the cover of nightlife, believing they won’t be caught because they’re far from home. In reality, we often find these men soliciting prostitutes night after night during their stay.
In addition to the emotional toll infidelity takes on relationships, there are serious health risks associated with sex tourism in Thailand. Thailand has one of the highest rates of HIV in Asia, with female sex workers facing an HIV prevalence of up to 20% in some areas, including Bangkok, according to AIDS Data Hub. STIs, such as the antibiotic-resistant “super gonorrhoea,” have also been rising, fueled by unprotected encounters with sex workers, as reported by the NYPost. The risks of contracting and spreading diseases through sexual tourism are higher than many people realise, especially when foreign men demand unprotected services from sex workers.
Men who cheat on their wives or girlfriends in Thailand don’t always fit the profile of habitual cheaters. Often, they are lured by the sense of freedom and anonymity they feel thousands of miles from home. We’ve seen numerous cases where men, once they arrive in Thailand, give in to the temptations presented by the country’s sex industry. It’s not uncommon for men who visit in groups to indulge in what they see as a “harmless” activity, promising each other they’ll keep their indiscretions secret.
Some men may also convince themselves that what happens in Thailand won’t affect their relationships back home. Unfortunately, this couldn’t be further from the truth. The psychological toll of betrayal, combined with the risk of STIs, often leaves lasting scars on relationships, even after the man returns home.
