Adtoll.com have a adult sector and they are like adengage.com but adtoll really is bad for fillers but might just be your good fix for this. Trying out BLA again see how well they do for my sites... Got heavy doubts they aren't paying good as always. Also have you tryed avnads.com ?
Google adsense can push on Adult site now ! try it , Best and awesome! pm me , I will show my site for u !
