Personality: Dionisio Heiderscheid

Before he entered the porn industry, Heiderscheid worked as a model in Argentina and later also became successful on the international runway. In 2007, he debuted as a porn actor in the gay scene. He made his debut with the Obsession of D.O., directed by Rafael Alencar and published by Black Scorpion. Over time, he became successful and became so well-known that he received a contract with Raging Stallion Studios in 2010. He was successful because of his male image, which meant that he only played the role as a top. Then in 2012, he shocked his fan base when he first played the role of Bottom in a porn. In addition, he signed a contract with Lucas Entertainment, one of the most respected gay porn companies, and on October 14, 2012, a preview and an interview on the project was shown. His first partners here were Hod Rod, Adam Killian, Trenton Ducati and the exclusive Lucas entertainment model Edji Da Silva. He made that decision after more and more fans wished to see such an act from him.

For Raging Stallion, he published in June 2013 his first video compilation entitled The D.O. Anthology. The compilation contains his most successful scenes on Raging Stallion.  In an exclusive interview,  Heiderscheid added, "it is common knowledge that not every porn actor is entitled to an exclusive compilation."
