I recommended to this brother a book I always recommend – Addictions: A Banquet in the Grave, Ed Welch, P&R, 2001, 297 pages.
Here is a tidbit from the preface to entice you should a need in this area or any other “rapid bodily experience” tend to enslave.
Addictions are ultimately a disorder of worship. Will we worship ourselves and our own desires or will we worship the true God? Through this lens, all Scripture comes alive for the addict. . . . since all Scripture addresses our fundamental disorder of worship, all Scripture is rich with application for the addict (p. xvi).
I wish I possessed a tool like this in the heyday of my battle with sexual addiction. If you fight the same or similar foes, see that you include this weapon in your arsenal for warfare.
