Come on, admit it. While we might talk about sex a lot, we're all fairly shy about revealing personal details, particularly when it comes to performance or problems in the bedroom.
Thankfully, this infographic by The Institute for the Study of Urologic Diseases took data from surveys of thousands of people, and has reduced them to 12 of the most common myths about sex. Turns out we've been getting it wrong all along.
First up is the myth that the size of a man's penis really matters to women. Well good news gents, it doesn't matter at all, with only 1% of women saying that it does.
The second myth is that people stop masturbating once they're in a relationship. Not so, says the report, which states that 85% of men still masturbate while in a steady relationship and 45% of women do too.
Number four on the list is interesting as it looks at how men and women select a sexual partner, the myth being that both sexes decide depending on the sexual prowess of their chosen partner.
However, this couldn't be further from the truth - according to the infographic - as men choose a partner depending on their fertility and women select theirs according to their ability to provide secure conditions for children.
Following on from this is the idea that men feel like they should always be ready to have sex, when actually they're just as complex as women when it comes to being up for it, with tiredness, emotional connections and not wanting to be unfaithful being cited as the reasons to why men won't have sex.
The sixth myth is one of the biggies: how long should it last? While the common thinking is that sex should take as long as half an hour, in reality the average performance time is 6-8 minutes.
Another one which we doubt many people are honest about is how often couples have sex. While we're sure some would love to say they get the chance to do it twice a day, in actual fact most couples average at 1-2 times per week.
Myth number eight is that women have to orgasm to have a fulfilling sexual experience. They don't. According to reports, 85% of women who say they experience problems reaching orgasm say they are sexually satisfied.
Surprisingly, the next misconception is that having a child will improve your sex life. But bad luck, apparently while having a child might give you a family, unfortunately it's likely to make your relationship worse.
But there's good news: using pornography can be beneficial to your relationship not detrimental as some might think.
Over 60s will also be happy as their sex lives don't diminish as some might be believe - with 60% satisfied with their sexual function and 64% of women content with theirs.
Finally, the last tale to be debunked is the notion that it's only men who suffer from sexual dysfunction, when in actual fact 40-50% of women and only 20-30% of men experience it.
