Being intimate

So my husband and I were having a discussion.. we were talking about kids and possibilities as to why we are having such a hard time trying to conceive a baby together. We have been trying for 3 years. Is it God's timing? Is it me? Is it him? What can we do differently.. it can't be making love because we we can't go a day without each other.. very rare do we take rain checks.. then the conversation switched to how often we thought other couples especially ttc couples that do the deed daily.. so question... How often do you and your spouse get down??
