A healthy sex life has many benefits, but things like work, personal choices, faith and even age can prevent that.
While there is no defining way of determining how much sex an individual should be having, it is possible to learn how much sex a certain age groups are having - so you can compare and contrast.
The Kinsey Institute, which research human sexuality, have conducted a study into that very area and these are their findings:
18-29 years old
Unsurprisingly it's the youngsters who are having the most sex.
Most people lose their virginity in their teenage years, with men losing it on average at 16.8 years, while it was 17.2 years for women.
This ignites a kind of sexual awakening, with the report indicating 18-29 years old are doing the 'no pants dance' an average of 112 times a year.
30-39 years old
As we mature, dozens of different things change in our lives.
Settling down and starting a family in your thirties is a very common trend but this does coincide with a drop in sexual intercourse.
However, sex isn't a complete stranger, as the report states that you'll probably be having sex a more than satisfactory 86 times a year, which equates to at least once a week.
40 - 49 years old
With middle age creeping in there's no surprise that there is a sudden downturn in sex for those over 40.
The study shows that people in this age group are having sex around 69 times a year.
This should be a surprise as kids, family life and other day-to-day stresses can seriously dampen anyone's libido.
The Kinsey Report didn't investigate the sex lives of older adults but the research is out there.
According to Healthy Women, there is a 40 per cent chance of sex two or three times a week between couples who have been married for more than 25 years.
That statistic drops to 35 per cent for couples who have been together for 50 or more years, but then jumps up to 42 per cent for those that have been together for 65 years.
If you are worried that your sex life doesn't match up with the numbers above, you should remember that these type of survey's only speak for a small amount of the population and shouldn't control how much sex you are having.
Whilst these figures will give you a good estimate to aim for, you shouldn't ignore the health benefits of sex too as it can lower blood pressure, ease anxiety and help your sleeping patterns.
