Women, how can the guy kiss you if you don't want him to?

It’s not clear to me how this happens, since I’ve never done it, but it sounds like I’ve been missing a bet. Like, if I wanted to kiss a girl, I should have just grabbed her and kissed her. She wouldn’t turn her head aside or kick me in the nuts or screamed bloody murder like I thought any woman might who didn’t want to be kissed would do; she would just have stood there and let it happen.

But I have heard so many stories where women seem to be passive, as if they have no say in the matter. If a guy wants to kiss her and she doesn’t want it, there’s nothing she can do.

I know this isn’t all the time, but still, it shocks me that it happens any of the time. Where does this passivity come from? Why do girls feel they don’t have any say in the matter (when they feel that way, anyway)?
