You should make a special effort to decide with your lover about modes of expression and communication between you. This will be very helpful, because your verbal messages often contradict your body language, at least from your partner's point of view.
It is usually best to tell your partner to listen to your words and ignore your non-verbal signals.
Because of this tendency, you tend to stay with an on-going relationship in which communication is already established rather than venture into a new affair where the rules must be created anew.
In the long run, your experiences - particularly your difficulties - in communication will cause you to become more keenly aware of and expert at co-ordinating your words and your non-verbal signals.
