I don't know about other people but I'd rather not be presented with tasteless fanny snaps being showcased on the site's home page. Opinions will differ of course but I believe there are a number of possible solutions:
1. Do not allow adult images to be showcased at all by hard coding an appropriate flag based filter.
2. Allow individual members to hide adult in the same way as they can hide nudity if they wish.
3. Get rid of members choice altogether.
4. Identify the members who voted for it so they can be subjected to a process of re-education, in the nicest possible way of course.
If development time is involved then perhaps members choice should be suspended for the time being.
