The present study focuses on sexuality education as an integral part of the fundamental right to education. It analyses relevant provisions of the Convention on the Rights of Persons with Disabilities and highlights related ethical issues. Study also shows that sexuality education is ideologically saturated and morally charged topic in Slovakia. In this paper we analyse context between social constructions of intellectual disability and sexuality and their implication for sexuality education. We outline some aspects of the right to sexuality education for persons with intellectual disabilities and discuss cultural challenges and related ethical dilemmas from the liberal point of view.
