Sex tourism isn't a crime but the major sex tourist destinations are known for underage sex as well. While they can't actually prosecute for underage sex directly it is illegal to leave the country for the purpose of engaging in underage sex. Besides, what they're actually looking for with sex tourism is kiddie porn.
