Like other psychiatric disorders, sexual addiction is a condition that affects peoples' relationships with others as much as it affects their own mental state. Individuals suffering from sexual addiction typically pursue sex through any means possible and often engage in risky forms of sexual activity such as exhibitionism, promiscuous sex with multiple partners, online sex, etc. It's easy to see how a couple's relationship may be challenged by the manifestations and reality of a disorder like this one.
