I know of an American guy in his 50s now who lived in Thailand for many years, shagged more than Hugh Hefner, and at some point realized that he was HIV positive, and this went on until around 2015 or so. He's now living on his sister's couch in the western USA and he acknowledges that he probably spread it far and wide. He has a Thai gf who didn't get it, and he flies her in to the US a couple of times a year and they have sex with a condom. I doubt this is an uncommon scenario. Honestly, to me, it's pretty obvious that Thai bar girls have too much mileage, are too jaded, and have banged more guys than most veteran porno stars combined. Thai men are bisexual drug-users. What do you think you're getting into?
