Symptoms related to intimate allergies vary. Frequently, symptoms will appear as contact dermatitis (irritation caused by a substance) on skin that has had direct contact with an allergen. In other cases, symptoms will appear in other parts of the body, such as general skin itchiness or nasal congestion.

Sudden, severe reactions such as anaphylactic shock can happen to some with intimate allergies, but such symptoms are rare. It is more common to experience less severe symptoms that unfold over a period of time. Symptoms typically occur within 30 minutes of sexual intercourse, but may occur hours or days later in some cases. Over time, patients usually find that their symptoms become worse and occur sooner after exposure.    

Signs and symptoms of intimate allergies include:

• Localized reactions
  
  
• • Swelling, burning, itching, pain, redness or blistering of the genitals
    
    
• Generalized reactions
  
  
• • Nasal congestion
  • Sneezing
  • Swelling around the eyes
  • Itchiness over the entire body
  • Hives
  • Wheezing
  • Anaphylactic shock (including swelling in the throat and breathing difficulties)

Reactions related to intimacy can affect sperm’s ability to move, which may inhibit fertilization. Women should also remember that vaginal itching may indicate other conditions such as a yeast infection. It is important for anyone who experiences these symptoms to consult a physician.
