Well it's the christian women I know who are boring I agree. As far as the purpose of dating some will tell you its only for when you are looking for a wife. Personally I just date for fun at the moment. Its something to do on some night during the week and have a good time going out with a cute girl and having dinner maybe sweing a movie or going to a concert.
I love your frankness
In my opinion, dating is a means to an end, and not the end itself. The end (purpose) is marriage, which is God's design. Off course, dating must continue (with one's spouse) after marriage.
Now, it is OK to date many women, as long as they are Christians and as long as one knows the limits set by God in terms of physical intimacy. Dating a Christian has its benefits, as there is no pressure to get physical. It teaches us to respect the opposite sex and be comfortable with the opposite sex. Dating the Christian way also challenges us to be more selfless; so it is good for our characters. It prepares us for marriage, because marriage challenges us to be selfless. A selfish marriage does not last.
Worldly dating could be very selfish. The world only teaches us to focus on self, and to use others for our own benefit. Getting physical is an important aspect of worldly dating.
As Christians, we must not conform to the pattern of the world (Romans 12:2).
I think, a kiss on the hand or a warm hug is enough to show the right type of affection. A kiss on the cheek may lead to something else, unless it a cultural thing to do.
