Bangkok

Bangkok city officials urged Thai couples to skip the sex this Valentine's Day and visit temples instead. Media surveys have shown teenagers in Thailand pick Valentine's Day as the perfect day to lose their virginity, according to the South China Morning Post.

Brazil

Brazil's version of Valentine's Day, "Dia dos Namaorados," translates to "Day of the Enamored" and is held on June 12. One tradition is to write down the names of all your crushes, put them in a hat and pick one name at random. The chosen name supposedly indicates who you should marry!

Denmark

The Danish way to celebrate V-day is with a secret-admirer guessing game called Gaekkebrev. They're love notes signed with dots instead of names. If the recipient guesses who the sender is, he or she gets a prize: an egg on Easter Sunday.

Finland

In Finland and Estonia, Valentine's Day is all about the celebration of friendship. Referred to as "Friend's Day," the holiday is called "Ystävän Päivä" in Finnish and "Sõbrapäev" in Estonian.

Germany

It's popular in Germany to give your Valentine a giant gingerbread cookie in the shape of a heart. The cookies typically have a few sweet words written on them.

Italy

For the full Valentine's Day experience, why not head to Italy and check out the holiday's namesake in real life? St. Valentine's flower-crowned skull is housed at the Basilica of Santa Maria in Cosmedin, Rome.

Japan

In Japan, it is customary for women to give men chocolates on Valentine's Day. One month later, on White Day, it's the men's turn to return the favor.

London

The London Dungeon, a British scare attraction, has been known to dish out a different kind of treat for your sweetheart on Valentine's Day. Instead of heart-shaped chocolate, how about a cupcake that resembles an actual human heart?

Slovenia

St. Valentine is one of the patron saints of spring in Slovenia. There's even a Slovene proverb that means "St. Valentine brings the keys of roots." The result is that Feb. 14 is a popular day to start working in the fields and vineyards.

South Africa

In South Africa, couples celebrate Valentine's Day much like in America. But one tradition they've stuck with dates back to a Roman festival called "Lupercalia," during which young girls pin their crushes' names on their sleeves.

Wales

A tradition in Wales for centuries, a hand-carved love spoon is a popular gift on Valentine's Day in traditionally Celtic cultures.
