You sound like you have a lot going well in your relationship already… Do you have a planned wedding date? (A light at the end of the tunnel, so to speak) And HomewardBound… does that mean you are coming back to the Church?
Here’s my usuall plug… Christopher West’s The Good News About Sex and Marriage. It discusses the frame of reference about sacrafice, well. Once I understood and accepted, it made loving my wife without sex almost as wonderful as with it. The only difference for you would be that you’d have to do that with your clothes on.
