Science says that sex can actually help, not hurt, athletic performance. But wary coaches disagree
Sex is permitted on these teams: Germany, Spain, the United States, Australia, Italy, Netherlands, Switzerland, Uruguay and England
Sex is banned on these teams: Russia, Bosnia and Herzegovina, Chile and Mexico
And the rules are complicated on these teams: France (you can have sex but not all night), Brazil (you can have sex, but not“acrobatic” sex), Costa Rica (can’t have sex until the second round) and Nigeria (can sleep with wives but not girlfriends)
The rules for the remaining teams are unknown.
Are some sex rules excessive? Probably. The two most common concerns about pre-game sex are that intercourse might make a player tired and weak or it could affect him psychologically. Studies have shown that the former is a myth.
