I took one of your sites and looked at the bounce rate. 50% is about the average and you are below that however, you do have some pretty high fluctuations. I used the Asianporncuties sites to pull this but don't know what you primary traffic site is.
When we see high fluctuations as we see here, there is normally a good indicator that your users are experiencing bottle necks at peak load times unless you have affiliates or SEO turning on and off. Slower load times will reduce conversions however, banner rotations can do the same.
Most of your users come from wildpornreview.com which I assume is your traffic portal. Those visitors mostly come from streamate.com a cam site which I assume you are using for traffic as well. Then there is your exit traffic which goes to google for the most part. Take that as you will but my assumption is that they are still looking. Either for free content or similar content.
I would love to talk to you if you are interested in looking into site optimization and perhaps Johnny V to talk about his new SEO product as it may just come down to where/how you are getting your traffic.
