When the Metro asked my husband Darren and me to keep a raw, unfiltered diary of our sex life for a week-long intimacy experiment, we didn't hesitate. We’ve been together for 26 years, married for 16 of those, and we’ve been through the absolute ringer as a couple. From nearly separating back in 2006 (and saving us by backpacking around the world to find ourselves), to surviving a devastating miscarriage in 2012 that nearly broke us, we have built an unshakeable bond.
