He was a prominent 'gay conversion therapist' in the US.
Sky News has reported that David Matheson, from Utah in the US, who was internationally known for discriminating against the LGBTQ+ community, has announced that he has divorced his wife and wants to start dating men.
He has now blamed his previous views on the "shame-based, homophobic-based system" of the Mormon church.
In a Facebook post, he wrote: "I enjoyed a happy and fulfilling marriage with my wife for many years. Overall, it was a beautiful relationship and being straight became a core part of my identity.
"But I also experienced attractions to men. Much of the time these were in the background. But sometimes they were very intense and led to pain and struggle in my marriage."
He added that his desire to be in "an intimate relationship with a man" became non-negotiable at the end of his marriage and that is why he ended it.
The founder of LGBTQ+ charity, Truth Wins Out, founder Wayne Besen told NBC News: "When they wanted an expert, they would go to him.
"When your expert is now coming out of the closet and dating men, I think that speaks volumes about how [the] therapy is damaging and ineffective."
Conversion theraphy is still legal in the US, however earlier this month New York became the 15th state to ban the practice on minors.
