The anime from 1998, which by now also has been followed by a sequel, was released in different versions on DVD in the US. The initially published Original Version by Anime Works is about 45 minutes long, meaning there are 15 minutes missing in comparison to the original Japanese Version.
The later released cut by Kitty Media, called Director's Cut, may be longer than the first one, but scenes including the breast touching and shots of sexual contact are removed in the movie. Again one can find a detailed comparison over here. The original Japanese version restores some scenes removed. The International Version was released outside of Japan and U.S. in 2000, but with different shots.
