Hello straight!
Welcome to PheromoneTalk!
mrseeker hits the eye of the bull with that advise. But please understand we’re not out to judge you here. 
A314 indeed is sexy, although its not a sexual pheromone, many users reported that wives and girlfriends and other women finds the confidence and alpha vibe it emits as attractive and sexy. It will certainly make your wife look at you twice with it. She will suddenly realize that you, her husband, is a man to trust, reliable, and to follow.
To cut the story short, I will recommend you the Ultimate Pheromone Intro Pack. It contains every pheromone you need in elevating your wife’s mood, towards your ultimate goal. You can read some real experience generated by using the UPIP’s pheromones here to at least give you an idea on what to expect, if pheromones were properly utilized.
But heed mrseeker’s non-phero advice too. One of the best way to revive your wife’s desire is by letting her see you as the same man she fell in love with years ago. Pheromones will help you do this, but the jokes that’ll make here smile, the surprises that’ll excite her, are surely not pheromone-produced.
Partner with mones. Mones will do their job, you do yours, and I assure you, you’ll get what you want. 
Happy pheroing!
