Hi Lioness 
There are a ton of threads dedicated to EoW. This one is a sticky at the top of the women’s forum. Newbie with a few questions… Bunny’s post should answer most of your EoW questions. 
The other sticky’s, also located at the top of the women’s forum, are also full of useful information and will be helpful in answering more of your questions about pheromones in general.
Hope that helps,
Bella
