@luukasztim,
In other words, you are a 12 year old kid who has no means of asking a girl out but you want to date a girl, ie be boyfriend and girlfriend, right? So sure, if that is your definition of dating, I guess it is possible. Just walk up and ask a girl to be your girlfriend, just let her know you won't be asking her to go out anywhere and do anything, but you would like to have her kissing on you and hanging all over you whenever the two of you happen to be together. I'm sure that will work.
As for the olden days, I just turned 55. I never remember dating anyone without asking her out. My parents dated each other for a while before getting married and I'm pretty sure my dad regularly asked my mom out. So I think you are greatly uninformed about how to do this whole dating thing, which is why I think you are closer to 12 than you are to 18. But of course, that is just my opinion/guess.
Oh, and by the way, it looks as though you improved your spelling. Congrats.
