An imam in Uzbekistan is offering free advice to couples on how to avoid having gay children.

During a sermon on marriage earlier this month, Rahmatulloh Saifutdinov, head of the Mirzo Yusuf mosque in Tashkent, told parishioners that homosexuality would cease to exist if couples just stopped thinking about other people during sex.

“For example, women are fantasizing about handsome Turkish soap opera actors,” he explained. “There are many such posts on social media by some married women. It’s like having three people taking part in the [sexual] intercourse.”

But Saifutdinov, who previously claimed homosexuality is ”a disease that worries the world community," isn’t being sexist . he warns men against fantasizing about other women while having sex with their wives, “because this may lead to the birth of a lesbian child.”

LGBT people face harassment and violence in Uzbekistan, where homosexuality is punishable by up to three years in prison. A gay couple was arrested and tortured by police in 2017, the same year a group of young Uzbeks posted a video of them stripping, beating and torturing a gay student. (The government condemned the videos, stating, “[Do] not to take the garbage out of the house for the outside world to see.”)

Former President Islam Karimov condemned same-sex relationships as a “vile phenomenon of Western culture” in 2016. “If a man lives with a man, or a woman with a women, I think that something there isn’t quite right,” he added, “or some change has happened.”
