Across the world, thousands are logging on to virtual worlds to meet, flirt and experiment with others. Free from the constraints of real life, they use text chat and sexy avatars to get it on in the digital realm. There's an enormous turn-on when the user realizes there's another person on the other side of the screen. Similar to MMOGs, MMOEGs offer players entirely sex-based environments. Sex therapist sees arousal along less gender-oriented lines. Desire is created by anticipation and by non-physical influences like imagination. The ultimate turn-on is freedom, the feeling that sexuality is an adventure you can design.
