I'm not sure about ALL, but I know it's very likely. And as far as I know it doesn't go away. With my experience at least. But, would being anxious all the time be better in order to have sex, or would you rather have sucky sex and not be anxious?
Becuase hopefully in the end, you won't need your meds anymore and can have all the good sex you want
Or, just talk with your doctor and see what s/he can do.
