I realise it's a sign of low self-esteem, but I constantly feel inferior to other men - the self-confident hipsters, the 'cheeky' laddish charmers, even other overweight nerdy guys.
Jealousy is such a destructive emotion, I know, but I'd just love to feel positive about myself, and actually believe that there are women out there who might somehow find me attractive (and yes, I know, self-pity is never sexy...)
