I have found a website is really quite unusual - it claims to be able to identify the gender of the user simply by analysing some text which they have written. All you have to do is copy and paste a small passage and hit ‘go’ - the site’s algorithm then scours the words you’ve used and decides whether you’re male or female. 
Apparently, the use of prepositions (around, below, above) and matters of statement (at, it, what) are predominantly male trends, whereas the use of more conditional language (if, should) and person pronouns (he, I, we) tend to be used more frequently by women. By calculating the density of your word usage, the engine reckons it can work out your gender.
I tried it several times - with an email which I had sent to a friend and also with two essays which I submitted at university - fortunately it came back male on all occasions!
But, a SHOCKING result - Gordon Ramsay’s most recent foul mouthed blog entry (here) came back as female! Very bizarre...didn't know f**k was a feminine word!
Check it out for yourself here but don’t blame me if it gives your gender back wrong - I’m only the messenger!
