Sadly, like so many on this list, Negron had serious problems with addiction — especially drugs, but also what he describes as compulsive sex. Sex, he reflects, eventually became meaningless, empty, and tied up with his drug abuse. He went to more than three dozen rehab centers before finally getting sober.

So no, Chuck Negron does not belong here because he claimed 1,000 or 10,000 or 20,000 partners. He belongs because his memoir makes clear the number was high enough that the exact math becomes almost irrelevant.
