A final note: it is possible to go to many Asian countries and participate in the sexual tourism scene without breaking any laws there and still be prosecuted when you return home because what you did would have been illegal in your home country. For example, the age of consent in Japan is 14; it is possible to legally have sex with a 14-year-old girl in Japan and then be prosecuted for child molestation, sexual assault on a minor, etc., when you return home. About 30 Western nations have laws to this effect. Those laws differ greatly from country to country and there is little information available on how often they are used.
