Jayne Ozanne, a Christian LGBT campaigner, has said she “spent years pleading with God to change” her when she went through gay-conversion therapy.
Gay-conversion therapy is not illegal, although the Church of England General Synod banned the controversial practice two years ago.
Ms Ozanne told talkRADIO’s Dan Wootton that it is also “condemned” by medical professionals.
“I spent years pleading with God to change me because I wanted to be loved,” she said.
“I wanted to be in a relationship of intimacy and yet the people who kept being attractive for me where forbidden fruit. I was trying to square a circle.”
The 2018 National Faith & Sexuality Survey, of which Ms Ozanne was the author, found that 68 per cent of those polled said gay-conversion therapy caused them subsequently to suffer from suicidal thoughts.
Whilst banned by the Church of England, some Christian ministries continue to offer therapy for people who “don’t want to continue with homosexual practices”.
Mike Davidson is the CEO of Core Issues Trust, a Christian ministry which offers such “psychotherapy and counselling”.
Mr Davidson told Wootton: “It is awful to hear what has happened to Jayne and the pain that she has been through but not everybody has the same experience.
“Some people come in my direction and they just for whatever reason don’t want to continue with homosexual practices.”
He added: “What we do is work with them and over time we find that their behaviours begin to change and their feelings dissipate – not in all cases.”
Mr Davidson also said that he had gone through therapy and “did not have the negative experience that Jayne did”.
He said it helped him “develop the best potential” he could to continue his marriage.
'The wrong side of history'
Wootton accused Mr Davidson of being on “the wrong side of history”, calling the therapy "barbaric".
“I feel so sad for you… Why would you not accept and embrace that you are gay and it is a beautiful thing?” he asked.
Adding: “I feel sorry for your wife.”
Ms Ozanne condemned Mr Davidson saying it was “that internalised homophobia that leads people to such distress”.
She added: “I am so glad that the government will make this illegal and I hope that they will criminalise Mike.”
In July last year, the government announced gay-conversion therapy would be banned as part of a government plan to improve the lives of LGBT+ people.
