As experience as shown that the field of law is no better educated than most other areas regarding sexual health, she wants to advocate for victims of sexual trauma and ensure that an individual’s sexuality is not shamed or unfairly judged by our legal system. This also extends to civil cases, such as family law, where spouses and parents may attempt to use the other party’s sexual experiences, alternative relationships styles, or kinks and fetishes to gain an advantage in court to the detriment of their former partners and co-parents.
