I'm just gonna go out on a limb and say that about half of those things are most often not symptoms or versions of "sex addiction." Consistent use of pornography, frequent one-night stands, prostitution (either being a sex worker or patronizing sex workers), exhibitionism, voyeurism, and more can all be part of a healthy sex life. It's much more about your attitude toward and relationship with those things than it is about participating in the activities themselves. Have lots of one-night stands because you want to and it doesn't interfere with your life otherwise? Good for you! Feeling compelled to have one-night stands and letting it absolutely control your life? Well then, that's a problem (but the vast majority of people don't fall into this category, I'd guess).
