Blue beard's room

In psychology, the key symbolizes the male sex organ.

Bertihan pointed out that the "key" that can open the door of the secret room refers to the male sexual organ. After opening the door, the key was stained with blood, indicating that the hymen was damaged during sexual intercourse, resulting in blood on the male genitals. In addition, no matter how to wipe the blood, it means that the lost virgin body cannot be recovered.

Therefore, opening the forbidden room with the key actually implies that the wife has betrayed her husband sexually.

In medieval Europe, if a husband found his wife having an affair on the spot, he had the right to kill her immediately. In the early medieval Belon Code, there was also a provision that "a man who cheated with a married woman should not save his life by any means in the face of her husband's sanctions, but should be responsible for his crimes and let the other party dispose of it".

However, Karl Henize Malagon said that the key Bluebeard gave his wife was actually the key to the chastity belt.

In ancient times, in order to prevent his wife from cheating, husbands sometimes sewed up a woman's vulva to preserve her daughter's chastity. Chastity belt is the product of this concept, which is opened and closed with a small key.

In early modern Europe, in order to prevent his wife from cheating, it was once popular for husbands to wear chastity belts for their wives.
