I feel for you! We've been going through this for the past two years. My husband's libido is directly impacted by the stress at his job. When he's on vacation, the sex is much better and more frequent... when he's back to the grind and stressed out, the sex dwindles again. I've talked to him about it several times. We're both aware of it and try to take steps to reduce his stress (i.e., eating well, exercising, participating in hobbies/sports together) and allow things to happen naturally. I realize it's not always that easy! I hope you're able to find the root of the problem and take steps to make things better! Best of luck
