I have visited or lived in 20 countries (many of them i visited way more than once, some around 10 times, and some are large and consist of many different regions), I can't imagine what countries are known for having women eager to hook up with strangers.

Unless one is planning to visit brothels or red light dustricts and pay for sex, I can't imagine what countries are known for random women "eager" to have sex with random strangers. It's just not a reality.

Women in very poor struggling countries often want to find a foreign man so they can hopefully escape poverty or dangerous situation by being able to move. So they'd look for relationship with foreign man for that reason (not hook up). There are also sex workers who might prefer foreign men as they might pay more.

There is no woman though (and certainly not many enough women to make country known for that) eager to hook up for sex with some random strangers unless they are sex workers hoping for good pay. I really doubt regular women expect random strangers to be a good lay just because they are foreign. It's not a reality.

I obviously travelled a lot overseas and in the states and love to travel despite it being expensive. I know others who travel a lot. I don't know anyone willing to travel internationally so they can hook up with strangers. Not only it's expensive, it could be quite dangerous to hook up and especially have sex with strange people in strange places . It could end ugly.

Ps I do know though that there is specific "sex travel", some men travel to countries like Thailand for that particular reason, visiting particular shady establishments within "sex industry". Perhaps that's what being discussed. But again that's "sex industry" and women are in it for money (and many are exploited against their will, sex trafficked, coerced by their own families etc)
