Hey what up
I clealy see your problem.Try to make yourself look better.Look at guys that attract girls and try to mimic their image.Do not try to impress a girl because the girl will look at you and think that you are really desperate for her and you will scare her away.Keep your self esteem high dont worry about what people think about you because i once had a problem similar like yours but i kept it cool. Keep your feelings smooth.If a girl ignores you dont worry there is many girls every where.Try to be smooth.
Smile at a girl when she looks at you but not a crazy smile just a cool smooth smile. Be hygenical. Girls love a guy with pealy white teeth,good breath ,groomed hair and some fly kicks if you know what i'm sayin.Well if you need more advice than that then i'll be happy to look out.
