I clicked on your Join button, and this leads to a PayPal sign-up page to sign-up for $5.99/mth, so even at a 70% payout for the Affiliates, that is only $4.20 a sign-up (and you keep the other $1.79/mth, woohoo).
This seems awfully low to me, even though the percentage is good, although I am not that familiar with the non-nude market (or why anyone would pay to see non-nude girls).
I did not see a 2257 notice on your site. Although your content is non-nude, it still includes content per the changing 2257 regs, which could potentially land you in some hot water if you are not careful (the government has tried to broaden the law in the past to include certain non-nude content, which some of your images could potentially fall under - naked girl touching her vagina with wet spots underneath on blanket, bottle of J&J baby oil covering a photo zeroed in on her vagina, etc - also, Johnson and Johnson's lawyer's may be contacting you about that too):
I noticed that you are using PayPal as a biller too. Be careful that you do not run afoul of PayPal, because you could potentially lose your account without warning (costing you and your affiliates money), if you are not in compliance with PayPals rules, so I would run your site by PayPal's compliance group in case you have not already done so (instead of waiting for them to shut you down).
Good luck, and I also would recommend that you start including video too.
