Most Helpful Girl
There's an archetype that's this but i can't think of what its called. Its the only real way a shy guy can impress girls that's actually really effective so long as you aren't ugly and dress nicely. The only way to really do it is by looking mad / focused all the time and being a mysterious, sarcastic rebel that looks like he needs saving. I personally find those guys very attractive whenever i come across them.
However if you're one of those shy guys that dresses crappy, smells bad or starts smiling and giggling when i approach you you're out of luck. Being shy out of any scenario that isn't the one i previously described is a huge turn off and there's nothing you can do to make women magically attracted to you besides gaining confidence.
If i may help you out some more on some observations iv made on mysterious guys who i find attractive. Always wear clean clothes. Try walking and standing tall, shoulders should be back, chin should be up, feet should be straight and your back / body should be straight and tall. Don't look excited when people call your name or look like you're looking all over the place like your looking for danger, just move and talk slowly. Lastly kind of squint your eyes and i know this sounds weird but don't smile too much. Try thinning every once in awhile but don't smile a lot. Its so sexy when a guy turns his head slowly and stares at me with focus, squinted eyes.
I don't know, im really subconscious and insecure myself but that's not a bad thing as a girl, im trying to help you because trying to impress a girl and being too shy is a death sentence for men.1THIS IS NOT RELEVANT ANYMORE
