Pro,
I have a few Dutch friends and I have asked them the same question. They see all sorts of topless girls over there on the beach and in parks and such and I could not really figure out why they would like to join a site like mine.
The part they like is the wildness and sexual craziness of the girls in my videos. Over there you can see all the nude bodies you want but it is a very calm boring non sexual thing.
Over here they are gyrating and humping each other and just plain Going Wild. They don't get to see that over there.
Cheers,
BV
