Sex: we're starting younger and stopping later

The third National Survey of Sexual Attitudes and Lifestyles (Natsal) involved interviewing more than 15,000 people aged 16–74 between 2010 and 2012, and then comparing the results with previous Natsal surveys from 1990 and 2000. 

The results reveal major changes in sexual behaviour with a fall in the age of first intercourse, increased numbers of sexual partners throughout life, and changes in partnership formation. 

There was decrease in the age at first sexual intercourse and a continuation of sexual activity past age 70, which the authors said emphasised that attention to sexual health later in life was needed.
