Refugee Cities. Planet of Women, #7

Joshua Miller was the president of Earth and refugee cities started appearing from another universe that had too many people.  Their Earth was sending them to Josh's Earth since it only had ten million people. With these refugees came a lot of new problems that he had to deal with. Then a plague came along which killed men only; which upset the balance between men and women. His human wives started divorcing him for various reasons which he didn't appreciate.
The human women frequently came back and wanted to be his wives again which caused him endless grief. He replaced the human wives who divorced him with android wives since they stayed with him.  They were also easier to get along with and were more attractive and better lovers. He decided he would have equal numbers of human and android wives. He occasionally thought that he would be better off with only one wife instead of having multiple wives.
There are some explicit romance scenes so this novel is only suitable for mature readers.
