Most women are like that, they may have already given in mentally, but they can't help resisting a few times verbally and physically. To put it nicely, this is called being reserved; to put it unpleasantly, it's called not wanting to take responsibility.
Just like when you pick up a woman at a party, even if you've completely attracted her, even if she is very willing to sleep with you, it's always you who has to begin by saying, "I have a lot of beautiful tropical fish at home, maybe you'd like to see them," or "If you don't mind, maybe we could find a quiet room to talk."
It's not that there aren't women who are independent, but most women always try to avoid making themselves look too promiscuous or casual in daily interactions, attempting to make the whole thing look like it was the man who took the initiative and led the way, the higher their position in the pyramid, the more so. Thus, a perceptive man should know when to be the gentleman and when to be the scoundrel.
