Roaccutane/accutane has killed my libido. what should i do?

Wait it out: I trust that you do not have hemochromatosis or a prolactinoma, both of which are common, easily-missed causes of diminished libido at your age. If this is an effect of your acne medication, you have the option of waiting until your course is over, or discontinuing it. If you choose the latter, work with your partner finding ways to give each other satisfaction that still work well. Best wishes.
