Dear LK: I'm happily married but hate our sex life. Should I ask for a divorce?

I've been in a loving relationship with my husband for years. We're incredibly compatible except for our sex life. The sex started off great, became less interesting over the years, and now it's non-existent. I'm considering divorce even though the rest of our relationship is fine. Initiating a divorce feels cruel, but I also feel like I'm settling and watching time slip away.
