Only college girls and kids who were teens and college student answer this?

i am 21 years old and i know i am a good looking guy, i am not the hottest guy around but i am good looking. my question is this. i am single and tell me if i am doing this wrong or if i am wrong. is it just me or the way you ask a girl out is different then the way you use to ask a girl out in the 90's. for example in the 90's from tv to real life.the way i saw it was a guy thought a girl WHO HE DID NOT KNOW, was cute. and would go up to her ask her out. and she would either say yes no or no not interested. because when a guy asks yo out he likes you not like you in the way i like you want i want yo to be my boyfriend but just like you. now its how the girl thinks and even the guy thinks what everyone and their Friends will say and if they don't wear the newest cloths or Finch. so is it me or have the way you ask a girl out changed or am i living in a Fantasy world
