Under the path Game Folder\Rack 2 Furry Science_Data\Rack 2_ Furry Science\translation, open the Localisation.xml file in any text editor, find the line ( <phrase id=‘DefaultDomTitle_male’> ) followed by ( <english>sir</english> ). You can change the ‘sir’ inside the line to anything you want, then save. There is also <phrase id=‘respectful_name_for_male’> and below this line will also be the name in the dialogue ( <english>Master</english> ). You can try adding additional variations for example ( <english>Master#Maestro#Lord</english> ). There is also an in-game dialogue editor, but it inconvenient.
Regarding clothing saves, I think it can't be done by default. Perhaps someone else can tell.
