Say what you will about 50 Shades of Grey, but experts claim pornography is actually damaging to relationships. A survey revealed that 70% of men between the ages of 18 and 34 watch porn at least once a month, and an increasing number of women admit to viewing it as well. The majority of relationship experts said they believe porn negatively affects relationships by creating unrealistic expectations and putting undue pressure on both men and women to look and act a certain way in the bedroom. Many also say they’ve recently seen a rise in cases of porn addiction.
