A male model has confessed to brutally torturing his journalist sugar daddy in a Midtown hotel for more than an hour — and then castrating him with a wine corkscrew — to get rid of “demons and a virus,” law-enforcement sources said yesterday.

“I’m not gay anymore!” accused killer Renato Seabra, 20, told investigators he raged to popular Portuguese fashion columnist Carlos Castro, 65.

Seabra then allegedly attacked the older man at the InterContinental Hotel in Times Square on Friday.

He told cops that he killed Castro “to get rid of demons, to get rid of the virus,” sources said. “The virus” does not refer to AIDS, although it was unclear what exactly Seabra meant by the statement, the source said.

Seabra confessed to the gruesome slaying Saturday night while recovering at Bellevue Hospital, where he was being treated for self-inflicted slashes to his wrists, sources said. He was then charged with second-degree murder.

“My son was not Carlos Castro’s lover,” Seabra’s mother, Odília Pereirinha, told a Portuguese TV station. “From the beginning, he never hid his sexuality, which is heterosexual.”

“My son, being a golden boy, who is so good, he didn’t do this.”

The couple had been dating since October, sources said, and was supposed to be vacationing in New York through Jan. 15.

But Seabra allegedly confronted Castro, telling him that he was not gay and was only using him for his money and influence, sources said.

The pair got into a heated dispute, sources said.

The model told investigators that he beat, kicked and punched the helpless Castro for more than an hour as the older man lay on the floor of the 34th-floor room. Seabra then allegedly bashed Castro in the head with a heavy computer monitor.

Seabra took a wine corkscrew to mutilate his victim, plunging it into one of Castro’s eyes and then using it to cut off his testicles, sources said.

The mutilation was long and gruesome. “It wasn’t a two-minute thing,” one source said.

Castro may have still been alive but was likely unconscious at this point, the sources said.

After the slaying, Seabra took a shower and put on a suit. At some point before leaving, he slit his wrists.

He was nabbed at Roosevelt Hospital after taking a cab there to seek treatment, officials said.
