i was on Sertraline for about 10 years. getting erection was very hard or getting aroused. Once its up though you can go forever it seems but not ideal. I finally came off them after my marriage was crumbling due to me just unaware emotionally. My new Doctor mentioned if i got reaccessed every year and said I never did. they just refilled it. I wasnt depressed for the last 5 years taking them as my life personally was great, but mentally i was a zombie. I finally came off them in October and it was horrible how I started feeling everything. My erections havent returned and my brain is mega whacked even to this day after stopping via tapering off in October. They are made to never get off, just my two cents. But on them by erection and being able to get one via my brain was hard. Off of them I ejaculate after about 1 minute and have 0 control because my brain is all over the place. Everyone is different but its hard on them and off. If you are depressed then a medical person can diagnose it but its up to you.
