Libido and Sexuality

I am 36 years old and not taking any AED's or any other medications (save for my asthma inhaler as needed). According to my OB/GYN, I am supposed to have arrived here in my mid-thirties in the prime of my sexuality. In fact, women are supposed to have the stamina of a young adolescent boy in our 30's...hence the show Desperate Housewives. And yet curiously, I have little to no sex drive at all. I want to know, what gives? I used to have a very high libido. Wanted sex several times a day just a few years ago. Now I've been thinking,"I could live the rest of my life without it." And this makes me sad because it is something that once was very important to me. But the weird part is that once I have sex, I enjoy it, it is wonderful. I can reach orgasm no problem and usually have multiple orgasms. I have read plenty on side effects of AED's on sexuality...but is there any information on the effects of seizures itself on sexuality? Also, can seizure effect the type of sexual desires one has? For example, can a person who was basically vanilla (traditional sexual desires) change over time and become someone interested in shall we say "alternative" experiences?
