Is Initiative Punishable?

I was always wondering whether it is appropriate for a girl to take the initiative in relations. On the one hand, we are taught since childhood that a girl should not call first or invite a guy to a date or (the most awful of all awful things) to be the initiator of intercourse. So, we have to wait like modest princesses in the towers till our noble knights will wake us up for love with the help of a magical phone call. But personally I find this process of waiting extremely boring and do not want to spend time in vain.
