is it just the tubes?
 

while tube sites are full to the brim, i find real people posting nude pics of themselves too for free.

many forums are full of people posting pics of themseves or girlfriends nude and x rated.

I found a local girl who was thinking nothing of posting full nude pics. She was not wanting cash. just happy to post.

it does make me wondewr why people would join a site (to pay) when so many people post free.

Why do people pay for sex when there is so much for free?

Because they get what they want, how they want it, when they want it, from
who they want it.

The real answer would be. "Why bother selling amateur content if so many amateurs give it away for free?"
