The second episode of the new thriller \u201cThose Who Kill,\u201d starring Chlo\u00eb Sevigny as Catherine Jenson, peeled back a layer on the character behind this aggressive young homicide detective. We learned in the first episode that she is a woman who experienced abuse at the hands of her stepfather, a judge, and who is driven by a sense of righteous vengeance. \u201cYou have to be worse than them,\u201d she tells a friend\u2019s daughter as she tucks the girl back into bed after a nightmare, referring to the monsters who plague the child in her sleep. When Sevigny\u2019s character becomes stressed and overwhelmed in episode two, she does something women who are sex addicts are all too familiar with: she finds a man she can seduce and control, in this case a married father, and tells him it will be a one-time event. When the man shows up nervous, bottle of wine in hand, the detective dismisses his pleasant gesture and attacks him. They have sex. Afterward, he asks Catherine\u2019s name but she refuses to give one. Instead she tells the man he needs to leave. \u201cActing Like a Man\u201d This seemingly small incident is instructive: people will tell us Sevigny\u2019s character is \u201cacting like a man.\u201d She\u2019s objectifying a submissive individual, making a sexual object of him in order to use him for her momentary purposes. She doesn\u2019t care about his name and doesn\u2019t want him to know hers. She doesn\u2019t want to see him again, a fact about which the man seems hurt. She has sought out the experience as an ameliorative to chaos; if Jenson can control someone sexually for a few minutes, if she can get a fix, she\u2019ll feel more in control. She has a history of abuse, and control is paramount. Jenson is doing something that is more often associated with male behavior; she is compartmentalizing and seeking power through the use of sex. In this case, the image is striking because she\u2019s female, but the way Catherine Jenson acts out is similar to how many female sex addicts behave. Female sex addicts often wrestle with past abuse and need to feel a sense of power and control. Seeking a \u201cOne-Down\u201d Partner In relationships of all kinds - whether long-term or a one night stand - power dynamics are often employed, sometimes with the awareness of their participants, and other times not. \u201cSymmetrical\u201d relationships are said to occur between peers, where issues are worked out with equal power and respect. Many relationships, however, can be considered \u201casymmetrical\u201d or power-based. In these relationships, one person is said to take the \u201cone-up\u201d position and the other takes the \u201cone-down.\u201d According to Samantha Smithstein, Psy.D., many people believe women are motivated to sexually act out due to neediness. Smithstein says this belief is based on social stereotypes about women and that for \u201cmost female sex addicts, the primary motivation is power - to overcome or master trauma such as sexual or emotional abuse - or loneliness - to attempt to combat the effects of emotional neglect.\u201d By engaging in sexual encounters in asymmetrical relationships where the woman is in the one-up position, she temporarily utilizes the power of seduction in order to arrest feelings of anxiety. But these episodes are not self-maintaining and the feeling of control never lasts long. In fact, the degree of acting out behavior, in terms of prevalence and type, may be directly correlated with the degree of anxiety in the sex addict\u2019s life. She acts out because she feels out of control; she acts out to bring about a sense of control. The more we understand about women\u2019s motivations in sexual addiction and the more aware we become of the ways past trauma impacts addictive behavior, the more insight we will have into gender-specific sex addiction recovery. Recognizing the patterns of sexual addiction is important in diagnosing the problem, but understanding the root traumas from which these patterns spring is the key to unlocking the behaviors and setting the addict free.
