Welcome to Pherotalk Scqueaky!
The great thing about this forum is that whatever situation you are facing there are others here with the same situation and pretty similar to give advice and support. 
I can think of one with a great thread that I recommend to all newbie married ppl. You are not a man but I think it works just as well.
I would also pop into the women’s section to ask the married women in addition to pheromones the techniques and other things they do to get that spark back into the bedroom.
Your GC is on it’s way!
