Is it unacceptable for a girl to make the first move and ask a guy out?

It depends on the guy and the girl. What kind of relationship are they trying to establish, if any? If the guy is old fashioned, he may not feel comfortable being asked out. On the other hand, he might be flattered that the girl asked. No The long and short of it is, that most guys are simply shy and feel awkward. Young women are more independent today and the guys can feel threatened. I don't blame them in many cases. I say yes! Not all women get up on the femanist plateau and some young women are old-fashioned, shy, and there is absolutely nothing wrong with this. You could nicely ask him out to a favorite hang-out or, go to a movie and something to eat after. Don't live on "what ifs" or "I should have." The way to ask a young man out is not with blunt confidence, but smile and pleasantly ask him out on a date. If he feels uncomfortable then by your body actions he won't feel cornered. No it is not wrong. Dating practices of today differ widely than yesteryear. Have fun with it.
