I took Levora and it killed my sex drive. Exactly like you say -- sex sounded great, looked great, but when it came time to do it, I just couldn't get into it.
I took Levora for about eight years before ever making the connection. I'd started it right when I came home from my honeymoon and just thought married life was sex a couple times a year.
I went off and my cycle was wonderfully regulated and my drive was through the roof within about three months!
You should really try a different pill if you must take the pill and you're having this kind of effect from Levora. My doc did switch me to another, something 1/35, and I could feel a real change in my libido, but that pill gave me other awful side effects (scary ones like migraine and edema), so I just went off altogether. I regret every minute my libido was suppressed from the pill.
Good luck in figuring it out
