Cybersex differs from phone sex in that it offers a greater degree of anonymity and allows participants to meet partners more easily.
A good deal of cybersex takes place between partners who have just met online.
Cybersex is commonly performed in Internet chat rooms (such as IRC, talkers or web chats) and on instant messaging systems.
It can also be performed using webcams, voice chat systems like Skype, or online games and/or virtual worlds like Second Life.
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.
It is also fairly frequent in online role-playing games, such as MUDs and MMORPGs, though approval of this activity varies greatly from game to game.
Some online social games like Red Light Center are dedicated to cybersex and other adult behaviors. Cybersex may also be accomplished through the use of avatars in a multiuser software environment. In Tiny MUD variants, particularly MUCKs, the term Tiny Sex (TS) is very common.
