SlickCash, has Lesbian Training, quite nice...dont send too much traffic to it tho so dont think my ratio sais much
Sapphic Cash has Sapphic Erotica, they dont have per SU but convert quite well for me, worth a try.....my ratio is about 1/600 (freesite traffic) on full 30/month or 50/2 months singups. $50/2 months is working quite well...
