Hey!
The user
CharlesFinley gave you a great tip: open everyone. When you're about to pay something on the supermarket talk to whoever is attending you. Do a banter line with a smile "this Oreo better not end on my hips" (with a smile at the end). Done. Doesn't matter the answer.
Ask people (attractive girls, if u want) on the street where is located a store or a library. Even if you already know the exact adress.
BUT
If your problem remains only in the realm of good looking girls, you can do this (which I believe is gonna prove a huge social proof for you): look less to the good looking girl you're speaking with. Talk over you shoulder, staring at the horizon in front of you (like you're thinking about what she says), look to her very little during the conversation. Calibrate the right timing to look at her (to look more and more) and I promise soon enough you'll be good to go.
And remember:
beauty is common, girls are competing men with other woman throug their looks all the time. You are the buyer.
Hope you improve. Go out and have some fun
