A 25-year-old South African man has now lost the use of his penis after his girlfriend poured acid on it — but he won’t press charges because “it won’t bring back my manhood”.

Humphrey Khoza was attacked with battery acid while he was drinking beers with friends in Cork village near Hazyview, Mpumalanga, on January 17.

The 17-year-old girlfriend, who cannot be named because of her age, said she was retaliating after Mr Khoza showed people a video of them having sex and “never intended killing his penis”.

The video was taken without her knowledge.

“Everything happened in a blink of an eye because I saw her when she was coming with a bottle but I didn’t realise that she was carrying acid. She just angrily called me a dog. She asked how in the world I could have done such an evil thing to her. It was only then that I realised that she was talking about the video that I took while we were having sex,” Khoza told African Eye News Service.

The couple had only been together a few weeks. He denies showing the video to anyone, however admits she didn’t know she was being filmed.

“We agreed to have sex, but she was not aware that I was filming the sex using my laptop computer. I did not intend to show anyone the video and I still don’t know how it got onto social media,” he said.

In the video, Khoza is seen pushing the girl, who was in her school uniform, to the bed. She appeared not to notice that she was being filmed while they had sex.

Mr Khoza said his penis would never work again due to the damage caused by the acid, but knew he was lucky to be alive.

He now has to urinate through a tube and has to undergo surgery.

He’d been advised to press charges against the girl but won’t be taking legal action.

“Even if I press charges it is useless because it won’t bring back my manhood. Her being in jail will just ruin her future because she is still young and I do not have the energy to attend courts,” said Khoza.

The girl told Times Live she heard about the video from one of her classmates. She thought they were joking — but when she saw it she said she “ lost my mind.”

The teenager told the website she was so angry she immediately thought of ways to make Mr Khoza pay for his actions.

The girl said, later, in an interview, “I never intended to kill his penis. I was just angry and all I wanted was to make him feel the pain I was feeling. I had to do something to show him that I was angry and wanted to hurt him so that he can see that he messed with the wrong girl.”

She said Mr Khoza deceived her even further by not wearing a condom while they were having sex.

She searched through her father’s tools for a wheel spanner initially but stumbled across the acid.

“I took it and went straight to his regular drinking place and when I got there I became angrier. I didn’t hesitate to pour the acid on him.”
