It does work, however with pheromones its best not to think too much about them. Its a “fire-and-forget” kind of spray, similar to a torpedo firing at a submarine. You spray them on after dinner and after the kids are gone (or just before you go to bed), enjoy a good moment with your wife, and before you know it you guys will set the whole bedroom on fire 
. But you gotta steer her a bit into that moment, I would recommend to seduce her a bit first after you spray, think about those moments when you were just married and young and then let the mones do the rest
EDIT: Just noticed your message about mobocaster’s journal: Mobocaster - Journal.
Its a great source for people around their 40-50’s who are just starting to use pheromones. Many of the stories on there are a great source of information for people, and he is one of the well-known users on this forum who gives great quality advice on pheromones for older people. Most people who use pheromones are between 18-30 years old, and when you get older the dosage on certain pheromones start to vary greatly.
