Final answer:
The psychologist most associated with the idea that culture influences sexual desire is not specifically addressed in the information provided. Sigmund Freud, although not known for this viewpoint, did influence 1920s morality with his theories on the unconscious mind's role in sexuality.
Step-by-step explanation:
The psychologist who claimed that it is culture that most influences our sexual desire is not explicitly mentioned in the information provided. However, the question seems to refer to theories of sexuality that underscore the role of cultural and social factors in shaping sexual behaviors and desires. In the historical context, none of the options provided (D. S. Marshall, Leonore Tiefer, Catherine MacKinnon, Sigmund Freud) are primarily known for asserting that culture is the predominant influence on sexual desire. Instead, Freud, for example, emphasized psychological factors, especially the unconscious mind. To address the review question provided, the popularization of Sigmund Freud's ideas indeed encouraged the new morality of the 1920s, which included a more relaxed attitude towards sexuality.
