I am looking for books that deal primarily with the halachos in Orach Chaim siman 240 and Even HaEzer siman 25. Due to the nature of the content it seems that the world has been reluctant to put out books that delve into the specifics of each halacha.

2 books that I currently own and I find very helpful are Kuntres Ufakadetah Navchah written by Rabbi Fink in New York. The other is Mishkan Yisrael written by Rabbi Shlanger in Jerusalem. (And of course, the Mishna Brurah).

Are there any other books that deal with these halachos in depth?

(Suggestions about other resources that might be helpful for teaching chasan classes are also welcome.)
