There are many reasons why a cookie could not be set correctly.
The fact that most of these affairs are concealed from offline spouses is indicative of the possible harm.
Consider this reaction: Just as casual sex is not necessarily inherently harmful, neither are online affairs.
One way of reducing the weight of these difficulties is to distance the online affair from offline circumstances—for example, by refraining from exchanging personal, actual details or by imposing other limitations on the online affair.
Thus, people may agree not to develop a relationship, permitting themselves only virtual one-night stands, or an uncommitted affair, or a promise with a partner to tell each other about each online affair.
In some circumstances, cybersex may in fact help a person through a rough period in an offline, loving relationship.
In such situations, cybersex may even be advisable—but still regarded as cheating.
In other words, a way to play out fantasies in a safe environment.
Other people are willing to concede that cybersex without the knowledge of their partner, ; nevertheless, some still maintain it's a type of "OK" cheating.
People, consciously or not, consider their online sexual relationships as real—they experience psychological states similar to those typically elicited by offline relationships.
