There are a number of popular, commercial webcam websites that allow people to openly masturbate on camera while others watch them.Using similar sites, couples can also perform on camera for the enjoyment of others.
In online worlds like Second Life and via webcam-focused chat services, however, Internet sex workers engage in cybersex in exchange for both virtual and real-life currency.
Cybersex can be utilised to write co-written original fiction and fanfiction by role-playing in third person, in forums or communities usually known by the name of 'A Shared Dream'.
There is disagreement over whether cybersex is a form of infidelity.
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.
Alternatively, it can be considered a form of sexual roleplay that allows the participants to experience unusual sexual sensations and carry out sexual experiments they cannot try in reality.
