Sadly, some people (even therapists) choose to use the term "sex addiction" to judge, label, and pathologize any and all sexual behaviors that don't mesh with their personal standards (religious, cultural, moral, etc.). They think:
He's been having sex with men. Clearly he's a sex addict.
She's had two affairs, so she must be a sex addict.
He has looked at porn three different times, even though that's a sin in our religion, so obviously he's a sex addict.
Meanwhile, other people try to use "sex addiction" as a catchall excuse for their sexual misconduct.
