How porn addiction can affect your sex life Hot and sweaty is usually good when it comes to getting frisky between the sheets, but the flu can give new meaning to the phrase "you give me fever". Sharing saliva with someone in a deep, passionate kiss is pretty much guaranteed to share any viruses. Surprisingly, though, regular sex can help ward off common colds and flu, according to one of the widest quoted studies on the subject. The research, done in 1999 at Wilkes University, showed that students who had sex up to three times a week had higher levels of an immune-booster called immunoglobin (IgA).
