Welcome to Pherotalk Rooby12!
The first thing I would recommend is that you read this journal for married men. There are some great advice and tips in here that will assist you and your wife :
The products I recommend are Ammunition; this is a sexual attraction pheromone to let your wife know that you are interested and it has a nice cologne scent which most women can appreciate. This is subtle and can be worn daily.
You will want to use Turn Up the Heat when you see you are starting to spark her interest again, this will ignite some fires in bed.
Instant honesty is a great product to use when couples want to get closer. It is a communication pheromone but for a deeper level of communication and this product can assist with intimacy.
Work, marital stress and sometimes not even communication can assist in killing the sex life in marriages. You will want to go deeper and try to figure out what the problem is with the use of the pheromones.
Good luck. 
Your GC is on it’s way!
