The sexuality is defined by the Sexual Education Treatment and Research Association (CETAD) as a natural and healthy part of all human beings and human life. CETAD also stated that each person expressed and experienced his sexuality in different ways (CETAD, 2008). Given these definitions, it should be considered that individuals with intellectual disabilities, like other members of society, need to have their sexuality as a part of their own existence, and their sexual needs can shape the behavior of these individuals. However, in the literature, it appears that individuals with intellectual disabilities are faced with negative aspects about their sexuality. It is stated in various sources that individuals with intellectual disabilities are those who have asexual, childish behavior that cannot control their sexuality (Ortland, 2008; Tutar Güven and İşler, 2015), are desperate, have no sexual desires (Bosch 2006; Treiber, 2011; Walter 2002), feelings and needs, are older children (Moll and Moll, 2010) and live extreme sexual lives (Bilge, Çeber, Demirelöz and Baykal Akmeşe, 2012). Due to these negative aspects, the sexuality of individuals with intellectual disabilities is forgotten or neglected (Walter, 2002). The sexuality of individuals with intellectual disabilities is now regarded as a "forbidden situation" and it is not possible for these individuals to live as they wish for their sexuality (Çelik, 2017). On the other hand, in some research results, a positive approach can be seen in the view of the individual with intellectual disabilities. It has been stated that the individual with intellectual disabilities does not differ in the sexuality from the normal individuals in general terms, and that, like every individual, these individuals will also want to live their sexual feelings appropriately (Seyyar, 2005). Thus, every individual with intellectual disability must face and deal with their own sexuality (Moll and Moll, 2010). According to Krenner (2003), individuals with intellectual disabilities have difficulty in living and managing their sexuality only according to the wishes of society. Individuals with intellectual disabilities do not have much knowledge in defining their own bodies, and can have difficulty in recognizing their bodies depending on their condition (Steel, 2014). Most individuals with intellectual disabilities may need lifelong care and support as they cannot meet their personal needs. The personal needs of these individuals are often fulfilled by their families. The families also identify housing and leisure activities for individuals with intellectual disabilities. As a result of this, the sexual life of individuals with intellectual disabilities depends on their own family's thoughts and attitudes (Treiber, 2011). The sexuality of individuals with intellectual disabilities is a problem, not only for them, but also for their families too (Betschart, 2009). It has been determined that the individuals with intellectual disabilities are able to live their lives as they wish and that the support of the sexual education to the individuals with intellectual disabilities is the most important factor in the protection of these individuals against sexual abuse (Çelik, 2017).
