It is highly unlikely that cockroaches could live in a human penis. Cockroaches are insects that prefer warm, dark, and humid environments, such as those found in basements, attics, and kitchens. The human body, and particularly the genital area, is generally not a suitable habitat for cockroaches.
If you are experiencing any unusual symptoms or concerns about your genital health, it is important to seek medical attention from a qualified healthcare provider. They will be able to assess your condition and provide appropriate treatment. It is not normal for cockroaches or any other type of insect to be present in the human body.
