Book excerpt: Internet sex, most commonly known by people as cybersex is more than just the use of a modern medium for sexual ends; it is more a reflection of today's fast-pace social life characterized by individuality, impersonality, materialism, and social isolation. Legally it is not acceptable and is considered as a crime. Cybersex refers to the extent to which an Internet user is influenced or affected by Internet sex. Internet sex has been likened to a kind of "sexual revolution" with more than 100,000 web sites featuring all kinds of sexual content, such as erotic photos, videos, live sex acts, and Web-cam strip sessions (Carnes, 2001; Cooper, Boies, Maheu, & Greenfield, 2001).
