P. S: I have also found social experiment regarding appearance and dating and it appears that girls are more keen on it. If you are intersted on watching it here it is:

I'd suggest you work on your own insecurities and find way to make yourself more attractive. I was shy when I was younger and I lowered my standards, it never works out because eventually you just lose interest in them especially sexually, and that's a big part of a relationship.
Shyness and nervousness can be overcome by forcing yourself to talk to women more often. Eventually once you've spoken to loads of them, and probably been rejected a few times, you'll realise it's no big deal and you'll feel much less nervous.
As for yourself, lift weights if you don't already, that way you'll attract more women. Even when I was shy I got approached because I had a good body.
