I have had similar issues. Like riot said, stressing about not having a sex drive will almost surely make things worse. There is a lot more to life than sex, and if you aren't interested maybe it is an indication that you should just let it be. Focus on the things that you DO want to do, and maybe the sex drive will come later. Maybe it won't ever be there. On the bright side, I believe that you can live a fulfilling life without sex. :-) Try living a happy sex-free life, and you might find that the impulses develop naturally after a little time.

Good luck. I know it's difficult. *hugs*
