oomis1105: “This is the first time I have ever heard my life that being a kallah is an erva.
I haven’t read this book, so I cannot intelligently comment on it, but having said that, anyone can write a book about anything, including a rabbi. Could someone please educate me as to the makor for a kallah being erva(not just the totally correct idea that a chosson and kallah have to be extra careful not to get caught up in hormones and emotions, which could lead them to be nichshal, but an actual makor that says the kallah is erva).”

Kalla b’lo bracha asura lebaala kenida (kesubos). Also any unmarried woman is assumed to be a nida which is an erva d’oraisa. Note that yichud is prohibited and has the severity of yichud d’oraisa due to her being a nida.
