A feature film in which a woman touches a man's genitals with her hand when he poses for a picture film biography

It seems you might be referring to a specific scene in a film or possibly a type of film that explores intimate or provocative moments. However, there isn't enough context for me to identify a particular film based solely on that description. If you're looking for recommendations for films that tackle themes of intimacy, biography, or unconventional relationships, I can certainly help with that! Alternatively, if you have more details about the film (such as actors, director, or a more specific plot), I might be able to assist you further.
