Surly the best way is for you to get affiliates.
I presume this is your affiliate site:
mvgcash.com
My thought is, vamp up your sites.
Lesbian Tribe - Home of Hot Lesbian Porn Young for your pleasure
The look just would not make me want to join.
It looks like you have great content.
But the design, is just yuck.
Bet the design done, then go out and promote the sites.
