Agency is the ability to act in a way to accomplish your goals. To have an agency in an area in your life is to have the capability to act in a way to produce the results you want. When discussing sexual agency, you have the ability to define yourself sexually, the ability to choose whether or not you want to experience sexual activity, the ability to choose how you want to engage in sexual activity, and the ability to stop or refusing any sexual activity. In other words, you know what you want sexually and what you don't want. You are capable of making and enforcing decisions about your sex life.
