The program offers 35 percent revshare for new sales and rebills, paid weekly through CCBill.
BBWLifestyle.com has been operating for two years.
"We started the site because we felt a need in our own search for swinging opportunities," BBWLifestyle co-owner Maria told XBIZ. "We had friends express to us the same frustrations that we felt, trudging through thousands of 'height and weight proportionate' ads. We realized there must be many others who would like a size-acceptance swinger community like ours.
"It started out around our kitchen table and it just evolved from there."
The website has 5,500 members worldwide, mostly in the U.S., Maria said. The site offers searchable member profiles with video and audio uploads, video chat, forums and blogs. A retail section offers video-on-demand and sex toys.
A monthly contest in the photo-rating section gives a free one-year full-access membership to the person with the highest-rated photo as voted by members.
"It's fun to see how sexy and downright dirty our members can get in front of the camera," Maria said.
