While I could attempt to show you an example of "Good Cybersex" i'm not going to. Instead i'm going to give you some pointers as have been relayed to me, and that i've learned over time.

Good Cybersex is best compared to a play where the actors write the story as they play their parts.

Cybersex is a fantasy and as such, not everyones tastes will run along the same lines.

It can be very very hard to have good cybersex with a stranger, because much like good sex in real-life, good cybersex takes skill, patience, and Knowledge of what your partner enjoys and doesnt enjoy. With strangers you might get lucky or you might have really bad cybersex.

Cybersex is a perfect place to experiment with fetishes and sexual activities that you may not yet be comfortable enough to try in real-life.

Be courteous. Because you got off doesn't mean its time to stop. As with sex in real-life, attempting to please your partner has great benefits and helps make the experience good for all parties involved.

Be Patient. Set a fair amount of time aside. Cybersex isnt and shouldnt be a hurried ordeal, its the building of a shared fantasy. Dont Rush Things.

I think that covers it for now, i'll probally come back and post some more things at a later date.
