I've never been arrested, but I do something illegal almost every day!
Do you sleep with minors in Thailand?
Good lord, certainly not! And I resent the suggestion.
Any form of sex which involves a financial transaction is illegal in the vast majority of countries, including some - like Thailand - where the law is not enforced.
Interestingly, in addition to the above, U.S. citizens are liable for prosecution for acts which are legal in the country they're visiting - for example prostitution in Brazil - but illegal in the U.S.! Land of the Free
