You guys need to get your self-esteem up, see yourself as the macdaddy of all the macdaddies
It's been said a million times before a girl won't think your fly if you don't even think so yourself.
Be happy with yourself nobody is perfect!!!!!
And if you aren't confident about yourself, maybe consider doing a martial art or somethinmg like that( I recommend kickboxing,muay thai,boxing). That will surely boost your coinfidence( or courage if you like ).
If anything else fails just use the JEDI-mindtrick on them
