Do not have a cam. Still I have had wonderful cyber-sex many times. It has been with women I have chatted with for a while and we have always known each other (as far as you can know anyone on the net) before having sex.
It has always been through our chat programs and it has been very satisfying. With the right person, both can get incredibly turned on, wet, slippery and feeling seriously wonderful
On the other hand - with the "wrong" person, it can be very disappointing.
Of course, it does not come close to making love in real life, with the scents, the sounds, the warm skin, the voice, the touch and the closeness of another person. But when it is okay, it is far better than masturbating on your own.
All the best,
Kathy
