Dyskinesia is an umbrella term encompassing a range of different movements. These are all movements that can be out of your control. Dyskinesia is very common in cerebral palsy.
Up to 50% of adolescents with cerebral palsy have an intellectual disability, as well as a physical disability. Adolescents with intellectual disabilities still need sexual health education, they just need it in a way that's more individualized so that they can understand it and use it.
