Do you think they actually need help? Personally as a woman I've always found shy guys very appealing. We don't all want over confidence and egos. Perhaps they need a little confidence boosting - as do many ladies as well - and there is lots of really good advice on the internet and in books, DVD's and so on. The only problem with some of these advice methods is that they can make you feel false when you try to follow their examples. So personally I would suggest just be yourself and if you are rejected at any time - welcome to the biggest club on the planet, we've all been there, males and females alike. Good luck.
