This book provides a comprehensive overview for those interested in research and promoting sexual health in older people, as well as a  go-to  guide on the topic of sexual behaviour in older adults. Sexual activity is an essential part of intimate relationships, though it tends to decline in frequency as people grow older. Nevertheless, for many older people, sex still remains an important part of their life. There s a common misconception that as people age, they lose their interest in sex and capacity for sexual behaviour. This is not the case, as a number of national surveys show. The new research presented here indicates that the less sex older people have, the more likely they are to experience mental and physical health problems. Men and women who reported a decrease in the frequency of sexual activities were also more likely to report a deterioration in self-perceived health.
