First of all, women should avoid pro-hormones all thogether. They have more unwanted sideeffects for women than just using less androgenic anabolics. Now, if you are on EF I assume you are juicing. That means you are going to be horny all the time. It could be that your wife as a normal, or even above average sex drive, but the fact that your's is off the chart from the juice could very well be the problem. I have as of yet to find a woman who wants to have sex for 3 or 4 hours a day, 7 days a week, for months at a time.
Another thing to consider is maybe it isn't an issue of sex drive. How are things going in your relationship? There could be a deeper issue here, which is often the case when a woman isn't in the mood to have sex with her husband/boyfriend.
Just my 2 cc's.
