Older individuals are less likely to declare themselves as being at the extremes of the sexual desire spectrum.[23] By the time that individuals reach middle and old age there is a natural decline in sexual desire, sexual capacity, and the frequency of sexual behaviour.[1] DeLamater and Sill found that the majority of men and women do not officially report themselves as having low levels of sexual desire until they are 75 years old.[8] Many would attribute this lull to partner familiarity, alienation, or preoccupation with other non-sexual matters such as social, relational, and health concerns.[6] ./cache/en-wikipedia-org-2224.html ./txt/en-wikipedia-org-2224.txt
