The chat room will load instantly and you can type in and send messages to that girl, also you can see her profile pictures and a lot more.
that means there are only 2 persons: you and the girl you like, thats why is called private room.
Some girls love watching big dicks on cam also while they play naked using sex toys.
To do that is your option and only if you like it too, simply click cam2cam button on your window and allow access to your webcam so she can see and hear you too.
Will explain later how is possible to let them watching you.
