The crazy roller coaster, which is my career in dating, took a rather exciting turn last month, when I was head-hunted by Time Out Group to spearhead their increasing involvement in the world of dating.

The average in most cities was under 3, with one stand-out exception.

The average man in Hong Kong, according to the survey results, dates up to 4 women at a time.

As long as I can remember, there's been a mythical rule about third dates and sex.

The survey results didn't really dispel that rumour - the global average is 3.53, which obviously considers more conservative cultures too.

Time Out asked survey respondents to rate both themselves and their average dates, out of 10.

The international readers were incredibly self-assured. Rather than punching above their weight, on average daters scored themselves as 7.3 out of 10, and their dates just 6.5 out of 10.

But if One of the questions on the survey was about how many people respondents dated at once.

Even in cities like New York and London, where apps like Tinder have made it increasingly easy to get a date, people answered relatively conservatively.

However for me, the interesting number '3' was in the comments by a Chinese man who answered the survey.
