Well, It should be normal but generally girls are shy to pop the real question. It has been the tradition from ages for a guy to ask the girl always.
But things are changing for the good and its completely fine for a girl to propose.

In the spirit of fairness though, ladies, will you agree to a date if a guy used these lines on you or do you expect something more artistic?
