How many people have you had sex with and how do you feel that compares to an 'average' person of your age?

So I told my girlfriend the number of women I had been with sexually - 14 at the age of 24 - and she told me that this was higher than she'd have guessed for a guy my age. I'd considered that wasn't many but It got me thinking that I have no real honest clue how this would compare with an 'average' individual of the same age.

What are your thoughts reddit? I suppose its common to think that everyone else is getting laid more than you?
