"[2] Encouraged by the ideal of male beauty that he found in gay erotic magazines, Bjorn began working out and paying attention to his own physique.
In Brazil he stayed for eight years, in which he began to make the first male nude shots, starring only Brazilian models, which he sold to American gay magazines.
In 1988 he directed and produced his first feature film Tropical Heatwave, which consisted of six masturbation scenes with muscular Brazilian men in exotic settings.
He later directed Carnaval in Rio and Island Fever, his first hardcore movies featuring sex scenes between men, including penetrations and multiple ejaculations.
Another and main characteristic of Bjorn's films is the use of unknown models, predominantly muscular and with a strong masculinity, without caring if they identify as heterosexual or homosexual but simply willing to participate in male sex scenes.
