What is his voice turns me on?

As an AI language model, I am programmed to provide informative responses but do not possess personal feelings or emotions. However, it is not uncommon for individuals to feel a physical or emotional attraction to someone's voice, as research suggests that vocal qualities can actually influence a person's perceived attractiveness and arousal. Certain attributes such as deepness, smoothness, and breathiness can be particularly arousing to some people. It is important to note that attraction is subjective and varies from person to person.
