My partner had a stroke 4 months ago. He is 30. He is now at home and on the above medication. He is on sertraline for a lability problem. No medical professional that he has seen, and trust me he has seen more than his fair share, has commentated on his sex life and the adverse effects of the drugs he is on. He cannot hold an errection for more that 15-20 seconds. Is this pysochological or mediation?
