I've done it twice, both with female friends that I knew for a long time before and our long distance IM chatting eventually led to flirting which led to cybering - basically simultaneous masturbation while typing shared fantasies...
heres my review:
Beyond the initial titillation of having "cyber sex" with somebody you know, it sucks. For strangers I'd imagine even that component is missing.
Worst part is, You are constantly interrupting your ministrations to type. Its like being forced to have a conversation while you are trying to fuck.
