What is the theme in Kiss the Girls by James Patterson?

The sexual urges of the modern man are frustrated by contemporary society. Casanova and the Gentleman Caller ignore society's constraints and choose the most fantastic and unattainable women they can find and take them. They do not abide by the modern mating rituals of long-term courtship. It is interesting to note that Rudolph does not need to worry much about this game. His handsome outlaw looks make him irresistible to almost any woman. He is not burdened by a wife—he is single and available. He is a very successful plastic surgeon. He seems to have everything a woman could want. Rudolph does not want to keep a woman. He is satisfied to keep little bits and pieces of them. He wants to sample all of the beautiful women.
