Do you know the signs of compulsive sexual behavior – also known as sex addiction? If you suspect your mate might be addicted to sex, then there are a few signs to look for. First, a little background on sex addiction. The diagnosis remains highly controversial – the disorder isn't even listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM), though it once was in 1987. So it's tough to diagnose, but therapy may help if the person is willing to get help. First, you have to ask yourself why you are even pursuing the issue – there's obviously a problem if so. If you're uncomfortable with the sexual habits of your partner, then you'll have to discuss it. If your mate is a true addict, then it will be tough to rebound from the betrayals, lack of intimacy and jealousy that inevitably will accompany your relationship. Red flags that may indicate sex addiction include obvious lies, like those made up when late coming home or financial fibs.
