I'm new to this forum, so maybe someone already gave a similar explanation, but this is how I started getting over my AA:
one day it was raining very hard, and I was going home, but didn't have an umbrella or anything like that... so I was just standing there, waiting for the rain to stop. Then I saw a girl with an umbrella walking in the direction I was heading, so I asked her if I could join her under her umbrella, just till the end of the street.
For myself, it didn't feel like I was trying something, and that made me a lot more comfortable...
At the end of the street, we kept talking for about 5 minutes... was really cool, and above all: I scored my first number!
So I waited again at the corner of the street, 'cause I still had a long way to go home and the previous girl wasn't going my way anymore... As I felt good, I decided to try it again!
Half an hour later, 4 walks with girls and 2 numbers later, I came come. It really felt like this was some sort of new chapter in my game-story!
So what I'm trying to say is: if you got AA, look for opportunities where you feel comfortable with yourself, where your main reason is not getting her number (in this case: going home without getting wet)... Good luck with it!
K-man.
