Yes, absolutely, mixing EoW into perfumes/lotions works! Some of us have been doing this for years. It’s an easy way to hide the stench of EoW. But we also use EoW straight to the skin without mixing it into perfumes/lotions. Using it straight, at first, is the way to determine your “sweet spot”. That’s the number of drops that work, for you, to stimulate the reaction you’re looking for.
How to find your sweet spot...
EoW stinks on it’s own so we try our best to hide that stinky smell by burying it under cover of perfume. So when using it straight it’s important to wait the 10-15 minutes for it to “dry down” properly before using a fragrance to cover that stench. If you immediately spray your cover scent over EoW before letting it have a chance to dry, you run the risk of the EoW stench rising to the surface. 
And no girl wants that to happen so that’s why we recommend/need to let it dry down. 
Also make sure you’re using a scent that’s actually strong enough to cover it!
