A sex addict died from a heart attack after taking a cocktail of drugs, Viagra, and erection cream at an orgy in Thailand.

The man, Khun Thep, 44, collapsed in a hotel suite during a monthly sex party with friends in Samut Prakan province on Sunday.

Thep, a taxi driver, had taken a woman to his room, but he emerged an hour later to inform his friends that he was feeling ‘unusually tired,’ police report said.

His friends later found him unresponsive and naked from the waist down.

“We celebrate like this every month. He came to our suite and just slept on the couch while we partied – we thought he was just tired,” a friend said.

“However, after I shook his body he wasn’t responding.”

Police found alcohol, a pack of Viagra, erection cream, and two unknown pills on the table next to the couch where they found dead. They also found several bottles of whiskey and cans of beer in the hotel suite.

Detectives said the 44-year-old suffered a heart attack after having “energetic” sex and consuming a cocktail of alcohol and drugs.

After taking the Viagra pills, the “Marathon Rub” cream had also been applied to his penis, police said.

Police spokesman Namasphong Madha said: ”There was nothing suspicious about the death at the hotel.

“However, it is embarrassing for his family as they did not know that he was there.”
