It seems it finally happened! Even more it is a "Sex Training Tour" according to this article. Extract:
"Young people in Da Nang, Vietnam are enthusiastically taking a Sex Training Tour jointly organized by the Da Nang Youth Union and the Viet Da Tourism JS Company to learn about sex from health workers and consultants."
How can they be not enthusiastic? Anyway what follows is more interesting:
"Unlike other tours, the sex training tour that began in mid-March at the Cham Museum in Da Nang is based on the Cham culture’s worshipping of sex organs and imparts sex education to youth through the precepts of the Cham culture."
I always knew Cham people were much nicer person than Kinh...too bad they lost the war against them.
