But research from dating service Match has led to a map being created of the average dating journey.
From the first drunken smooch outside a kebab shop, to the moment you bring your first child into the world - they've surveyed 2,000 men and women to see when they hit these milestones.
Would you hold hands with someone on the first date? Many people (34 per cent) said they would wait between one to two weeks before making that leap.
Over a quarter of Brits said they would wait up to two weeks to have sex with a new partner, while 23 per cent admitted to waiting for a month.
Within a month, 60 per cent of respondents said they'd introduce their new squeeze to their best pal.
Worryingly, over a third said it would take them a month to be comfortable enough to get naked with the lights on.
On average, after five months of dating, couples say "I love you". And many see this as the perfect time to update their social media relationship status (Do people still actually do this?)
After an average of 10 months, couples went on their first holiday together.
The average couple got engaged after two years, married after just over three years and started a family after four years of dating.
Research also found 27 is the average age British daters meet their partners.
Match do know it's not one-size-fits-all, obvs.
Kate Taylor, Match's dating expert, said: "While each relationship moves at its own pace, daters are often reassured by comparing their experiences with others'.
"We all ask our friends, 'When did you know your partner was The One?' or, 'How long did you wait before you kissed?'.
"One statistic I disagree with, is how long UK daters are waiting to get undressed with the lights on. We always advise daters to love your imperfections. Strut your stuff proudly! The right partner for you will love you for the naked truth, inside AND out."
Damn right, Kate.
