Hi there,
I personally do not know what this would mean at all. Having sex requires being awake. One has to take motoric and conscious actions with the intend to reach an orgasm, the finality of all sex. The only thing most of us know about is 'passing out' after using drugs or alcohol whereby ONE partner might still use his partners body for sexual pleasure, while she is asleep, passed out. I am pretty sure that many people, if not most, experience a least once in their life time sleeping with someone after alcohol intoxication and not recalling anything next morning. If partners trust each other they usually have no problem finding out that their partner had slept with them while they were 'passed out'. If someone is of hysteric nature or has severe conflicts within the relation ship anyway or has no trust in her partner then, yes, it might become an issue. But, NO, having sex while being asleep WITHOUT influence of drugs simply does not exist, I believe. Journalists or media people are not always right, neither every doctor. Perhaps this was a miss understanding?
