I was just wondering what are some the ways that married couples can enhance a marriage? Here is my story.

I have been with my husband for almost four years and married for almost two years and for the most part I am pleased with our marriage, but there are times that I wish that my husband and I were more intimate and did more things as a couple. I am not saying that we don't have a good sex life because we do, but it seems like the only time that we get intimate is either when he wants it or one of us has been gone for a long period of time, is there anything that I can do to help us become more intimate? What are some things that we can do as couple other than go out to bars and movies?
Thanks for all your help
