I'm 17, been wearing contacts for a year and a half, but I never got used to the feeling. I kind of want to go back to glasses, but I never got checked out with them (I was 15/16 though and possibly not finished with puberty, I'm not sure), and now I do. I know that's petty, but still.
Librarian fetish - look it up. Girls with glasses DO get passes. You know why? Taking off your glasses is like the beginning of getting undressed and it forces him to look at your eyes which you can then use to communicate to him your desires.
My guy loves my glasses but he takes them off to see my eyes better because there are scratches all over the lenses. I hate glasses because of the smudges and scratches, but I wouldn't want contacts ever.
