No sex

My husband and I never have sex. Ever. It happened one time in the past 2 years. I’m 37 years old and this makes me angry. We’ve been married 14 years and it’s always been an issue and just keeps getting worse. He never initiates it and never thinks about it. If I try to initiate he has an excuse. This has made me miserable for 14 years. What do I do about it?
