Oh I hope your correct about the age thing. You mean as I get closer to 40 my sex drive will take a turn for the better. Oh think God. My meds make my sex drive almost non existant. But thinking back to the good ole days, To say your not in the mood and it have nothing to do w/ meds would be odd.

Besides medications to not be in the mood could be due to stress, illness, Do you ever have a cold and just feel yuck and think no sex please. It could be due to relationship issues. Hurt feelings, anger, sadness. I have these issues and that adds to my "NOT IN THE MOOD" So it may not be all the meds fought. It might be partially the situations fought.

Of course to be in the mood, well horney pretty much explains it. Or overly interested at the least. Hope this helps.
