The only problem with them is that when you register for a "Free" account all you see is women in clothes waiting for you to pay hundreds of dollars only to take their bras off.
That is why nobody belives the phrase "Free Live Cams" any more. They are not free!
But there is One Cam Site that is Truly Free. It is called Chaturbate.com
Ont he site you can watch full shows (girls, boys, couples) and you don't have to pay anything.If you like the shows or you want to request from the models, you can tip them, but this is totally voluntary, it depends on you.You don't have to tip them to watch the shows.
For Signing Up you only need an email!No credit card, no addresse, nothing.
