Being a slut is not the same as an addiction. Having sex as a hobby is not an addiction. Being a billionaire golfer with a liking for blondes is not an addiction.
As has been said, when the need for sex overtakes everything else in your life, and your work begins to suffer, and your friends and family never see you, and you cease to care about anything other than fucking, then you might have a problem. Describing something as an addiction is not a judgement. You might decide to live out the addiction. Go for it. But for some people, having their behaviour so out of sync that it worries them, there is nothing wrong with seeking some calm, sensible, non judgemental advice about how to fuck themselves silly and still pay the rent.
