Marco Aurelio Denegri

Marco Aurelio Denegri Santa Gadea (16 May 1938 – 27 July 2018) was a Peruvian intellectual, literary critic, television host and sexologist.

Early life and education His father was Julio Ernesto Denegri Cornejo (his great grandfather was Marco Aurelio Denegri Valega), and his mother was Leonor Santa Gadea Arana. He attended Colegio San Andrés (formerly Colegio Anglo-Peruano). He later studied law at Universidad Nacional Mayor de San Marcos,

Career During the 1970s, Denegri was the editor of Revista Científica y Artística de Cultural Sexual – Fáscinum. Its first issue was published in April 1972.

His career in Peruvian television began in 1973. From 1997 to 2000 he hosted A solas con Marco Aurelio Denegri on Cable Magico Cultural.

He wrote articles for various Peruvian newspapers, which have been published in "De esto y de aquello" by Ricardo Palma University.

During his youth he frequently visited Jirón Huatica in Lima, a meeting place for prostitutes and their clients. In "Miscelánea humanística" he drew a map of the location as he knew it.

He was also a witness to peculiar sexual encounters. In one of the airings of "La función de la palabra", he said that together with a group of people he witnessed a technical intercourse session which involved great endurance in resisting the urge to ejaculate. Denegri related that he saw a male prostitute enduring 45 minutes of passive oral sex without ejaculating. Furthermore, in an interview conducted by journalist Raúl Tola, Denegri said that he attended an ejaculation contest which consisted in ejaculating up to the farthest distance. Amused by his story, Tola asked him where could one find such contests, to which Denegri only replied that several such contests exist.

He was an audiophile and music lover and a Peruvian cajón lover; for this reason he introduced the term cajonística to refer to the art of African-Peruvian cajón playing.

On December 10, 2025, the Universidad Nacional Mayor de San Marcos received a donation of 3,900 books and magazines belonging to Denegri.

Death He died on 27 July 2018 due to pulmonary emphysema.
