Am I suffering from shrinking yang?

This is because the pudendal muscles suddenly contract after being stimulated by cold air, so keep warm and don't worry too much! Shrinking yang is much more serious than your situation.

Shrinking yang is also called shrinking yin, also known as shrinking yang or shrinking yin. It refers to a disease characterized by sudden contraction of penis, testis and scrotum. The biggest feature is that the patient suddenly feels the penis contract or shrink into the abdomen, resulting in extreme fear of death. Traditional Chinese medicine believes that it is mostly caused by the invasion of cold pathogens or damp-heat pathogens, and yin deficiency and excessive fire can also be induced, which is closely related to meridians such as foot Jue Yin, Du meridian, liver and kidney.
