Mr. Big Fat Dick, born Marco Martinez on December 16, 1985, in Vienna, Austria, is a Caucasian Austrian male adult performer, producer, and director. Standing 6'1" (186 cm) tall and weighing 204 lbs (93 kg), with blue eyes and a bald/shaved head, he is known for his muscular build and large endowment matching his provocative stage name. A self-admitted sex addict with a pre-pubescent obsession for porn fueled by VHS tapes and magazines, he spent 15 years in disciplined bodybuilding before entering the industry around 2015 at age 30.
Initially hustling under aliases like Marco Martinez with small studios in Prague, Berlin, and Budapest, he gained prominence via DDF Network, collaborating with Evil Angel, LetsDoeIt, LegalPorno, Digital Playground, and Reality Lovers. Specializing in intense dominant scenes—rough sex, anal, BDSM, squirting, and VR—he has over 130 titles and nominations including AVN Best International Sex Scenes (2023), XBIZ Europa (2021), and Venus Best Actor (2017). He runs mrbigfatdick.com for custom content, emphasizing gym discipline, alpha supremacy, and straight male domination. Resolutely heterosexual, he prioritizes fun, safety, and horniness on set.
