So I got in to a serious relationship with a woman. I’ve been wearing pheromones since our first date which was months ago, I still wear pheromones every time we meet. From our perspective we are a good match, we think alike, we talk a lot and we seem to have very similiar interests and world views. So my question is what will happen if I stop using pheromones? I’m afraid to try it out, turning off the pheromones might ruin her sexual attraction towards me and her interest could fade. What should I do? Do I have to use pheromones for the rest of my life every time I’m with her?
Pheromones are not the be all and end all of A healthy relationship, as long as you continue to make each other happy you will be set, pheromones can help things go a little smoother at times but it is you she is interested in not the cologne you wear.
If the sex has been good and she respects you, cutting off the pheromones will have little effect. I base this on personal experience.
Of course, a love affair loses its sexual heat after a year or two anyway. Later, you can use pheromones to re-spark the relationship.
Thank you for the input 
Super valid question, and GHOST and Whitehall have it right - she got her impression of you while you were using pheromones - but if you’ve upkept your relationship then not using them will not suddenly change her opinion of you.
You know the whole “first impressions” thing 
Just keep a healthy relationship and always be congruent.
