2014 World Cup sex bans: Jurgen Klinsmann takes a 'casual approach' with the U.S. team

U.S. coach Jurgen Klinsmann has made it clear that unlike their Mexican counterparts, his players are free to have all the sex they want during the World Cup. Klinsmann was asked about his stance on the matter by Fusion TV after Mexico manager Miguel Herrera took a firm position in favor of abstinence for the duration of the World Cup.

“I think we are very casual in the way we approach things. Their families can come pretty much any time. They will be at the games, they can come by at the hotel, we will have barbecues together,” Klinsmann told Fusion's The Soccer Gods. “Every nation is different. I’ve played in different countries where, you know, you didn’t see your girlfriend or your wife for two months. That was more the Italian background when I played in Italy. So I respect the Mexican approach because it’s more their culture at that moment. I think we have a group of guys together and an environment together that is very open, it's very casual. But once we go on the field for training and also for the games, we are very serious and down to business.”

Given the U.S.'s difficult group, the bedroom might offer the team's only chance for pleasure while in Brazil, so for the sake of morale, Klinsmann's approach probably makes sense.

Here is our updated list of participating teams' sex rules...

Against sex (or variations of it) at the World Cup

-Mexico: "If a player can't go one month or 20 days without having sexual relations, then they are not prepared to be a professional player," said Mexico manager Miguel Herrera. He later claimed he wasn't planning on enforcing the policy before adding, "Forty days of sexual abstinence isn't going to hurt anybody."

-Spain and Germany: Strictly prohibit sex before matches, but significant others are allowed to visit on off days. Spanish players were robbed after allegedly having a party with prostitutes at their hotel during the 2013 Confederations Cup, though.

-Bosnia and Herzegovina: They have an absolute sex ban while in Brazil thanks to coach Safet Susic, who wants military discipline from his squad. But he did add, "They can find another solution, they can even masturbate if they want." Maybe he's hoping that limitation breeds creativity both on and off the pitch.

-Chile: No sex and no soft drinks.

-Brazil: Players are allowed to have "normal sexual intercourses" but sexual "acrobatics" have been denied.

-Nigeria: Former national team captain and coach Christian Chukwu has recommended a sex ban to current coach Stephen Keshi. "In my days as a player even as a coach, I made it a point of duty to stay away from women because sex has a lot of spiritual things attached to it," says Chukwu. It's unclear if Keshi will take this advice, though.

Not against sex at the World Cup

-The United States

-France: Coach Didier Deschamps has said he won't completely prohibit players from having sex, but "it all depends on when, how and how much." When the press pointed out to him that there is a brothel just 500 meters from France's World Cup base, Deschamps threatened to keep "files" on the journalists who go there, just as they do with the players.

-England: Roy Hodgson hasn't taken a definitive position on the matter yet, but when he led Switzerland to the 1994 World Cup, he initially banned sex, and then changed his mind before the tournament began. Switzerland finished second in Group A that year, just ahead of the USA.

-All other teams, presumably: The fact that this is still an issue to consider in the year 2014 is more than a little weird.
