My wife and I run a decent sized porn site, Ask Us Anything! **NSFW**
My wife I started an adult site called Barelist at the end of 2008.
URL: http://www.barelist.com NSFW
The site now gets around 100,000 unique visitors a day and is growing well.
Feel free to ask us anything about the site, the adult industry from an affiliates perspective, working with your spouse on an adult site, etc...
