I appreciate the suggestions Torrilin, but I just want to jump back in and say, as admin of the site: It is totally valid for some members to not want to see certain subjects, no matter how they are framing them in their minds or trying to flip the scripts, etc. There are a myriad of reasons why this might be the case. It's also quite a lot to try to do mentally when the main object is to study the pose and learn from it, sometimes in 30 seconds or less, without also having to come up with a whole backstory for the pose.
On another note, it occurs to me that requesting "only nude" models would remove a large quantity of these costumes you don't want to see, Meow420! Unless, of course, you don't want to see the nudity either.
