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.

If you see that there are unexplained expenses – particularly those that require large amounts of cash (after all, a cash purchase from a prostitute or sex store, for example, wouldn't leave a paper trail) – then there may be a problem. Take a look at the length of your partner's previous relationships. A history of serial dating and lack of commitment may indicate sex addiction. Finally, if you know for a fact that child abuse and/or molestation was part of your partner's childhood, factor it in with the other habits you're questioning. People who feel ashamed of sexual activity may be addicted, so listen to those thoughts. There is help for people who suffer from sexual addiction, and it's believed that up to 5 percent of the American population is addicted. Sex Addicts Anonymous is a good start.
