Obviously, I'm not a physician, but stating that someone has this addiction simply because they think about it all the time or have issues with temptation can often be inaccurate. Young, famous, wealthy men have intimacy options almost on tap, and taking up beautiful women on the offer to go home more frequently than is advisable doesn't necessarily demonstrate an addiction.
True addicts of this vice see it become a constant preoccupation of their time in some form or another. They not only do the above, but they also seek out every available immediate option for satisfy the urge: They "take care of themselves" multiple times daily, pick up homeless people for the deed if they spot one, and cannot get through most days without "relief" several times. It's bad.
I wonder if he "self-diagnosed" or his therapist literally diagnosed him.
