Some men 'allergic' to sex
Do you get feverish and run down after a romp in the sack? You may very well be allergic to your own semen, scientists have discovered.
Known as Post Orgasmic Illness Syndrome (POIS), it is believed to affect about 1% (and possibly more) of the male population worldwide. Symptoms of the syndrome include intense anxiety and discomfort and of course, headaches and itchy eyes and nose, sneezing and sore muscles - all symptoms that hint at the start of flu.
