difference between 'such as' and 'for example'

I am a japanese pretty girl.
Please let me know the difference between "such as" and '"for example".

And I am a handsome gaikokujin... but this is not the sort of forum for such hanky-panky.

'For example' is slightly more formal perhaps than 'such as', but the main difference is that 'for example' can follow the example, where 'such as' cannot.
