DON'T even think about gaming women until you get your AA and INNER GAME sorted out.
There is a great post on this and what to do but i'l try and water it down.
Basically whilst walking smile and say hi to any females that pass your. Grandmother, high school slut, pregnant teen, it DOESN'T matter, you just have to erase the association in your brain that women are DIFFERENT which thus makes it difficult in approaching because you furthermore think what to say next, then after that, then after that again. The more you think the more your subconscious tells you not to, it states the complete opposite to what you WANT to do. Thus employ the '3 second rule'.
I had the same issue, I went to a bar with my mates and just beamed smiles...not a perverted, I-want-you-bad-baby smile, I thought of a sincerly funny moment which made me crack up and beamed that and said hi.
98% of the time it results in a conversation for a few minutes then eject if shit gets sticky.
All your after here is to battle the AA demons and become comfortable with female interaction and to perceive her as another guy (in terms of ease of conversation).
After around 3 of these nights/days you will remarkable change and your onto the gaming stage, but for now keep this up, it will work I guarantee
Goodluck mate
