Three points, for what it's worth.
1. Your website doesn't rank. There are 31 domains on 13 IP addresses linking to it. Most of those links are affiliate links so will not pass on link juice to the site. You have one keyword in the top 10 and another in the top 100 out of common keywords associated with porn.
2. As others have said, Natalie looks completely disinterested and this does nothing to help sales. Without trying to sound mean or nasty, she looks like she just doesn't want to be there and it shows in the content.
3. Your affiliate program would do better on CCBill, because that's where the largest pool of affiliates pushing smaller sites is. That's not a reflection on ModelCentro, more a reflection of your site.
