In some contexts cybersex is enhanced by the use of a webcam to transmit real-time video of the partners.
Channels used to initiate cybersex are not necessarily exclusively devoted to that subject, and participants in any Internet chat may suddenly receive a message with any possible variation of the text "Wanna cyber? " or a request for "C2C"/"C4C" ("cam to cam" and "cam for cam", respectively).
While it does not involve physical contact, critics claim that the powerful emotions involved can cause marital stress, especially when cybersex culminates in an Internet romance.
In several known cases, Internet adultery became the grounds for which a couple divorced.
The exact definition of cybersex—specifically, whether real-life masturbation must be taking place for the online sex act to count as cybersex—is up for debate.
