Contextual adult ads
 

Are there any sponsors that support/offer contextual ads, similar to Adsense or YPN? I'd like to add them to a site and the closest I've found (meta-wise) is geo-targted ads.

Try clicksor
 

These guys offer adult? I didnt see any advertisers mentioned on their site.

I also should have mentioned that I wasn't looking for a CPC deal, just a sponsor banner/creative which is related to the search term.

I believe PHPAdsNew has/had this ability but when I tested some while ago, it was a pretty restrictive search.
