However, only the fellas will feel the benefits.
Sex is reportedly the best cure for hayfever.
Forget the nasal sprays and antihistamines and take up riding if you're suffering from hayfever.
Experts say sex causes the blood vessels in nasal passages to constrict helping to clear out your blocked nose and dry up those runny eyes.
The symptoms of hayfever ease after sex, according to the research at the Tabriz Medical University in Iran.
Airborne allergen expert Max Wiseberg told The Sun that the research "suggests that sex could help with the symptoms, so that may be something to consider although there may be some practical issues around timing and locations".
"However there is probably not a more pleasant way to deal with the symptoms of hay fever."
However, the symptom relief is linked to ejaculation so just the fellas are likely to gain any relief.
