In his film, "Your Husband - The Unknown Being", Oswalt Kolle explains typically male behaviors that are often hard to understand for women. Men love differently. If both partners were better informed about male sexual processes, many misunderstandings could be avoided. Kolle had the courage to use a naked male to educate the audience about male sexual organs, because only this satisfied his ideal of true equality between men and women.
