Keeping the spark alive!

Taryn
My husband and I have even together for almost 10 years, married for 3. We have had several ups and downs in the frequency in which we make love. We've gone months without and been fine. However, we just overcame an extremely difficult few months, and the last five days have been amazing. We've made love every day and are back to the feistiness we've not had in years, maybe since the very beginning. So, my question is, how can we keep this going? We've had times before where we had a good run for 2-3 days and then it fell off. 
We want to make this last and keep this going. We are really having fun and getting back to a great place. We are willing to try anything(well, almost everything-swinging and other people are not our thing). What have you done? What tips do you have?
