This question gets asked alot, but I've had alot of success with WEG (
www.wegcash.com) over the last year or so.
A new program that's not really 'adult' in relation to porn, but it definitely targets adults is FastSize. I just started promoting it about a month ago, and I've been doing real well with it. I'd encourage you to check it out and see if it'd work well with what you're looking to do. I know it's a shameless plug, but it may actually work out for you
