A new survey has discovered women would like intimacy to last for 25 minutes 51 seconds.
According to the findings men also want around the same, their reported ideal was 25 minutes 43 seconds.
However the gap between expectations and reality is rather wide.
The research, by saucydates.com which asked 3,836 people, found that love-making around the globe is not lasting anywhere near that amount of time.
Those questioned in the US and Canada reported having sex for the longest around 17 minutes. In third place were the British, whose steamy sessions last an average of 16 minutes and 58 seconds.
The Aussies came in fourth, with a performance of 16 minutes 34 seconds. And lastly, Indian participants proved to have the least stamina with an average of 15 minutes 15 seconds.
But what happens if loss of libido results in a sex life that is non-existent?
It is a common problem that affects many men – and women – at some point in their life.
Houston sex therapist Mary Jo Rapini explains the eight reasons why this could happen and what to do, to Women's Health.
1. You feel resentful
If you are angry at your partner, it's very difficult to feel in the mood for sex.
"A woman needs to feel readily loved and connected to their partner," said Rapini.
"Resentment prevents you from feeling free to escape during sex, which is key to wanting and enjoying it.
She suggests spending some quality time together and talking about the issues afterwards.
2. You don't feel good about your body
Our body image plays a huge role in how sexy we feel. Research suggests women suffer most with this.
The Journal of Sex Research declared that how a woman feels about her body has a stronger impact on sexual functioning than even the menopause.
A national survey by the Daily Mail showed that 52 percent of women have avoided or postponed sex, even when they were in the mood, because they were too self-conscious about their looks.
Practicing self-acceptance is helpful, says Rapini.
3. You're a serial dater
Having more sexual partners doesn't make you a better lover, argues Rapini.
She warns that if you are jumping from one relationship to another, you may have an underlying fear of intimacy – and sex is never going to be that good and fulfilling.
She says there is nothing wrong with enjoying casual relationships and having fun, but asks people to be aware of why they are doing it.
4. Your birth control pill
According to NHS Choices, hormonal contraception can negatively impact your libido.
This includes the combined hormonal contraception (pill, patch or ring), the progestogen-only pill, the contraceptive implant and the contraceptive injection
Rapini says it's easy to blame hormones when you lose your sex drive when it may be psychological issues.
Indeed, a 2016 study in the Journal of Sexual Medicine reported that hormonal birth control wasn't a strong factor in libido in long-term couples – and that relationship factors have more of an influence.
5. You feel jealous
If you feel your partner is looking at other women it's unlikely to make you want to get intimate with them.
"You should definitely tell your partner you don't like when they do things like check out other women or Google women right in front of you,' said Ms Rapini.
She says it's important to clearly express what you expect from the relationship and not feel like you're being too demanding or controlling.
6. You have a medical issue
There may be underlying medical causes of a low sex drive, and that includes the side effects of certain medications.
Everyone's sex drive is different – there's no such thing as a 'normal' libido. But if you find your lack of desire for sex distressing or it's affecting your relationship, it's a good idea to get help.
7. Your lover is not satisfying you
Rapini says many women in their mid-thirties say their partner is a great husband and father, but they're not good in bed.
If this is important to them, she advises them to speak up, but be sensitive.
Sex makes us feel vulnerable: we're sensitive to criticism and quick to get performance paranoid if we're told we aren't doing something properly in a non-too-subtle way.
There are ways to communicate what you want in bed without hurting their feelings or making them feel inadequate.
8. You've been together for a long time
It can be difficult to keep the spark alive in a long-term relationship.
Research suggests it's women who go off the boil first, losing interest in having sex after just a year with their partner.
They are four times more likely to not care about having a steamy night of passion than those in shorter relationships, found Southampton University.
