How can my husband and I improve our communication?

S. asked:

We are lacking in this area. I am very expressive and like to talk openly about my feelings, he is more reserved and prefers to bottle them up. We both have quick tempers and are stubborn. We butt heads alot, and I think it is because our communication skills aren’t very strong. I know that communication is one of the most important things in a marriage, so what are some tips on improving communication?
