There are a number of reasons why a person may get hives on their penis. Hives on the penis have been linked to scabies, angioedema, STDs, and various allergic reactions. Treatment options will depend on what has caused the hives. It is important to see your doctor about hives on your penis or genital area, because they could have an effect on reproduction.
If you have hives on your penis, try to narrow down the cause by thinking about things that you have been exposed to. Hives can appear as a result of cold or heat exposures, exposures to various foods or other allergens, or even emotional states. Make a list of any possible reasons that you can think of, including sexual interactions, and take it with you when you go and speak with your doctor. Taking Benadryl or another antihistamine in the meantime is a good thing to do, especially if you cannot see your doctor immediately.
One of the major reasons that people may have hives on their penis is because of angioedema, which is similar to urticarial. Angioedema is characterized by a spontaneous swelling which occurs in areas of the skin or mucous membranes. It is caused by a buildup of fluid which leaks from thin-walled blood vessels. It is the same as having hives, but it occurs underneath the skin. Sometimes it will be accompanied by hives, and in men and boys the scrotum and penis may be involved. If the hives on your penis is caused by angioedema, the hives will likely be accompanied by a mild pain or burning sensation.
According to AllergyClinic.com, there are a number of possible causes for angioedema. They are:

A rash caused by scabies is often accompanied by hives. The rash appears as tiny red bumps that are extremely itchy. It may be accompanied by hives, and these may be hives on your penis. Contrary to popular belief you don’t have to have sex with someone to have scabies. It can be acquired by any type of skin-to-skin contact and sometimes even through bedding and furniture. However, if you go see your doctor about hives on your penis, be prepared to talk to him about any sexual intercourse you have had as of late. Treatment involves the application of creams and lotions which contain insecticides. Thoroughly cleaning the house, vacuuming well, and washing all the clothes in hot water will be needed to abolish your scabies infestation.
Thrush is sometimes mistaken for hives on your penis, and could even be accompanied by them. Thrush is a type of yeast infection which can occur in men. One symptom found in thrush is sores which look like hives on the head and foreskin of the penis. These sores are painful to the touch. Consult with a medical professional immediately if you notice any of these symptoms.
