What westerners might call 'casual sex' -- sex without the framework of a relationships that implies various other promieses/committments -- is normal, and also not likely to be spoken about frankly, especially to a reporter, and much less a British one.
Sometimes I'll witness a young woman asked about it at a social gathering (as people have a few drinks and speak more freely). "I don't have anybody... I can't remember the last time I slept with somebody," she might say. What she means is that she doesn't have a steady boyfriend, and thus it is certainly none of your business who she's fucking.
Or I will see a guy asked about it. "Well, romance is too complicated with all I've got going on... I've learned to live without it," he might say, with just the right amount of sheepishness. What he means is that he is seeking only sex that doesn't come with implied commitments and hassle.
These two people might very well end up leaving together.
