The topic of sexuality and romantic relationships of people with mild to moderate intellectual disabilities was examined. We developed a questionnaire to investigate the 76 respondents' sexual knowledge, attitudes, experience, and needs. During the interviews, observational data were gathered to check the validity of the instrument. Results show that sexuality and romantic relationships are important aspects in the lives of many persons with intellectual disabilities. Male respondents generally reported more sexual needs than did females. Correlations were found between sexual knowledge and attitudes and between attitudes and experience or needs, suggesting that general behavioral models may be fruitfully used to further explore the topic of sexuality among people with intellectual disabilities.
