As in the real world, not everyone asks to have sex, they simply feel the moment out or know what the expectation is.
While most people have webcams today, many people choose not to use them.
Please spread the word about 321 Sex Chat on twitter and any other online venue you frequent that allow sites such as this to be posted. While both allow for typing, talking or camming with others they are completely different types of sites.
Most "cam sites" have a host, usually a girl who is paid credits for her time while she strips.
But "free" adult cam sites (like this one) are actually chat sites with webcam capabilities where the people on cam are not paid.
