sexual addiction does not just imply requiring sexual contact - it tends to include needing sex often and from lots of different partners to the point where an individual is putting their health and lives at risk by having sex with people they don't know, who's STI status they don't know, often falling in with potentially violent partners, using illegal drugs and blacking out. The sex itself isn't the danger or even the addiction, so much as the pattern of (as Dr. Drew would put it) chaos in a person's life.
