When I first started my current meds I had no sex drive for awhile but I also had a severe mood episode and was hospitalized.  After about 6 months or so I started feeling more normal and my sex drive came back.  I know the side affects of many meds is decreased sex drive but I guess like every side affect some get better in time and some don't.  I would talk to my p-doc about it and see if after a period of stability if it doesn't get better I would want to try something else.  Also, I did find out that even though I had a low to no sex drive if I would at least try I could achieve some satisfaction if only knowing I was there for my husband (ex now).  Also, a depressive mood definately removes a lot of desire and I always shoot for north of normal instead of south.

Could be all the medications that you might be on.  Or it could be your age (although I don't know how old you are).  If you are not getting along very well with your significant other, that can also be a factor.  Good luck.
