The above are great for dating.
I also suggest
flirt4free and
Chaturbate if you have any cam white labels.
Pimproll for white label tube sites. These come with ads and pop-ups built in. They also allow you to put in links. But there is nowhere to put like Iframe or banner ads.
Easyxsites is also a tube white label and they allow you to use from select ad networks like plugrush and chaturbate. This is the only white label I know that allows you to use your own ads iframes and banners.
