Generally, online affairs are easier to perform and put the agent in a less vulnerable position, as the chances of getting caught or being hurt in other ways are considerably reduced.They are also perceived to involve a lesser degree of betrayal, as they involve more imaginary elements and the degree of neglecting the partner's interests may be lesser.
Accordingly, cybersex is about sex, but a form of sexual encounter involves experiences typical of other encounters, such as sexual arousal, masturbation, orgasm, and satisfaction.
Indeed, people consider cybersex to have a high degree of psychological reality—but many do not consider it to be consider it to be infidelity.
The private nature of online affairs may make them less painful for the betrayed partner as well.
Moreover, when online affairs are revealed to the significant other, which is done more often than when offline circumstances are involved, it could be considered as something less than cheating.
In reality, though, the issue of online cheating is more complex—especially when it concerns sexual activities involving actual interaction with other individuals.
People, consciously or not, consider their online sexual relationships as real—they experience psychological states similar to those typically elicited by offline relationships.
Consider this reaction: Just as casual sex is not necessarily inherently harmful, neither are online affairs.
But they may be so when participants are also involved in another primary offline relationship, because of the harm imposed on those partners.
Time spent in that world can help them their actual world, while not giving up on having exciting, even emotional experiences.
