The porn is just a gimmick. There are hundreds of maps that go unplayed because it is really hard to make a popular map. I made the maze challenging, so you might not even get to the porn anyways.
YOU MUST play this map with friends or at least people on a public battle.net game because half of the fun is finding the secret chat commands. The chat commands do random funny and silly things, and they are easy to guess.
Give it a try.
