It has been revealed that organizers have arranged for a record 150,000 free condoms to be packed into dispensers around Games' venues this year. The number of condoms is 50,000 more than Beijing Olympics.
Women's football goalkeeper Hope Solo, who won gold with the US team in China, reckons that randy athletes will turn London 2012 into the Sex Olympics and condoms will be an essential part of the athletes' kit.
She revealed there was wall-to-wall sex at the Beijing Games, and the action is set to be even wilder in the less-stuffy UK.
Organisers are shipping in 50,000 more condoms than were available in China.
"There will be a lot of sex going on," the Daily Star quoted Solo as saying.
She confessed she was shocked by the antics she witnessed in Beijing.
"I've seen people having sex right out in the open," she said.
"On the grass, between buildings, people were getting down and dirty.
"Athletes are extremists. When they're training, it's laser focus. When they go out for a drink, it's 20 drinks.
"With a once-in-a-lifetime experience you want to build memories, whether it's sexual, partying, or on the field," she said.
Hope revealed that she and her team-mates partied with Hollywood actor Vince Vaughn, 42, and comic Steve Byrne, 37.
"At some point we decided to take the party back to the village so we started talking to the security guards, showed off our medals, got their attention and snuck our group through without credentials, which is absolutely unheard of.
"None of us slept that night. I may have snuck a celebrity back to my room without anybody knowing, and snuck him back out. But that's my Olympic secret," she said.
London 2012 organisers asked condom makers Durex to supply more contraceptives than for any other Olympics for the 23,500 competitors and backroom staff.
"The last thing the organisers want is to run out," a Games source said.
"Athletes get through a lot in the pressure-cooker atmosphere of the Games," the source said.
At the Sydney 2000 Games, organisers thought 70,000 condoms would be enough but had to bring in 20,000 reinforcements.
Beijing ordered 100,000 in 2008, as did Vancouver for the 2010 Winter Olympics.
"The condoms will have a sexual health message on the packaging," a London 2012 spokesman said.
