Olympic Games Village becomes the hotbed of sexual activity for athletes from every discipline.
Olympics provide one of the few occasions in the sporting calendar where athletes of all disciplines intermingle - and with the training and competition heating up, testosterone levels are at an all-time high.
According to one high profile member of Team GB, the combination is a recipe for sexual heat.
"People often think that because you're an athlete you have to behave a certain way," the Daily Mail quoted him as saying.
"And of course, when we are competing, we are very well behaved. But once our events are over, we need to let our hair down.
"Within the village, teams from different countries are segregated in different parts. Everyone is walking past each other, meeting athletes from different countries.
"They'll start off just swapping pin badges, or some kit. Then as the event progresses, you start visiting other people's dorms, exchanging Facebook or Twitter details and telephone numbers. It starts from there," he said.
He revealed that in the first week while athletes are preparing for their events, everyone is very focused, then they start getting knocked out in the heats, or their events are early - meaning those athletes have a lot of free time - and a lot of excess energy to expend as well as beginning to get bored - and that's when things heat up.
"In the second week, it starts getting more exciting," he said.
"That is when a fellow Team GB athlete and I arranged to meet a couple of Ukrainian athletes from the track and field team who wanted to have a night out in London.
"I got us on the guest list at Mahiki, and the cocktails were flying. There was lots of dancing. I kissed one of the girls - a pretty blonde field athlete with big blue eyes.
"We invited them back to our dorms for some more fun, and ended up leaving at around 1am to go back to the Village," he said.
The Team GB member said that they were not supposed to take girls from other teams back to their dorms - but that as long as the athletes had accreditation to get into the village, the security would usually turn a blind eye to girls being brought into men's accommodation - especially if they were rewarded with pin badges or free kit.
"We snuck the girls into our quarters after I ran upstairs to get the security guards some pins," he said.
The Team GB members had previously smuggled some contraband alcohol into their accommodation (alcohol was forbidden in the village, and no athlete indulged until they had finished competing): a bottle of blueberry Absolut vodka and a bottle of Disaronno - which they opened and drank together.
Just minutes after the four entered the Olympic accommodation, they found themselves entering into a very steamy situation.
"My friend took one of the girls to the bedroom we shared, while I started kissing the other one in the sitting room. She had an amazing body, obviously, and she was hardly wearing any clothes - just tiny hot pants and a small top," he said.
"Just a couple of minutes after we'd started kissing, she stripped off and stood there totally naked.
"She was asking me to get a condom and have sex with her. I told her she couldn't have me yet as I love to tease and be in control but she kept saying she wanted me.
"Five minutes later the Ukrainian girl who had been with my friend came out of the bedroom - she was wearing just a T-shirt and French knickers. She looked at us and said, "don't worry about me, I'm just getting a drink."
"I thought I'd test the water, so I said to the girl I was with that I would have sex with her if she had sex with her girlfriend first.
"They seemed really keen, giggling and kissing each other. It was clear that one of them at least had done this before.
"Before I knew it, they were kissing each other and I was kneeling on the floor between them. I don't need to give you the details, but let's just say I was having fun - and so were they.
"My friend from Team GB was a bit nervous, but soon joined in kissing the girl I'd been with earlier," he added.
