Any link with a is a new addition to the list
Please note that some of the centaur sites are a bit more "adult" oriented due to the habit of female centaurs not being much interested in clothing....most sites have warnings when such is the case but not all, so if such things offend you or you're underaged, please tread carefully. Next time I update I'll put warnings with the sites which need them.
