The Reverend Martin Ssempa, a homophobic pastor in Uganda who is well known for his lectures against homosexuality has stunned television viewers in Uganda by demonstrating with fruit and vegetables how he believes gay men and women have sex.

Appearing in a discussion with a trans activist on the Ugandan television talk show Morning Breeze, Mr Ssempa launched into a graphic description of gay sex.

Arguing with Pepe Onziema, a trans man who is a well known activist for LGBT rights in the deeply homophobic country, Mr Sempa explained that gay sex is wrong because the “anus is for exit only”, demonstrating with a banana.

He explained: “When you are homosexual, you have more chance of experiencing death from HIV – why? When you take a man – this is a man’s genitals,” as he picked up a banana “you insert them into the intestine – ok? They put their genitals into their excretory system – this excretory system is not designed to receive, it is only for exit.”

The pastor then tried to explain how Mr Onziema has sex with another woman. He said: “For woman what they do is they begin their sexual acts, because she does not have the equipment, they begin to use their lips… so the mouth is used to lick the other person that is number one, it creates [gonorrhoea] men and lesbians have gonorrhoea and oral syphilis.

“Number two, because they don’t have the equipment, they begin to use gadgets like bananas.” As he picked up a bunch of fruit and vegetables he added: “they use carrots, they use bananas they use cucumbers, and other metalised ones, and they put them insides themselves…because they are not normal.”

Mr Onziema said: “My family loves me as I am.” He exclaimed to the host of the programme: “I cannot believe you would put me on this show with a hooligan!”

In 2010, Mr Ssempa stunned reporters at a press conference by showing them hardcore gay porn.

The following month, he showed extreme gay porn to his church congregation that included minors.

He has also claimed that gay people eat “poo poo”.
