The results were determined by a three-stage process
1) We started with open nominations. Readers were free to nominate any 2023 nude scene.
2) After reviewing all the nominated scenes from the reference page, readers took part in a qualifying poll. (The results are shown here.)
3) In the final election, the voters were asked to pick one and only one scene as the one they considered the best of the year.
There was no doubt about the top three. There was a big gap between first and second, between second and third, and between third and fourth. The next group is tightly bunched, with only thirteen votes separating 4th place from 14th. If we re-did the vote on another day, any one of them could be significantly higher or lower within that group. There is a significant drop from fourteenth place to fifteenth, introducing another tight group from 15th place to 25th, with only six votes separating those places.
