Sexual health is not a necessary component for one's overall health and well-being. Those with disabilities are more vulnerable to abuse and require protection against sexual abuse and misconduct. Considering that the mentally disabled are at a unique risk of sexual predation, their sexual security is paramount.
As a society, we consider the sexual protection of vulnerable populations a necessary concern. We protect children from sex acts and protect the victims of sexual criminals; the prevention of abuse and exploitation of the disabled is in the same category.
