Hello im 22, i tried Propecia two days ago hoping i wont get any bad side effects, unfortunately i was after 2 days of taking it im unable to get an erection, also im not as horny. i only can get an erection when trying to masturbate. because of this after 2 days of taking it i have decided its not for me. ive stopped taking it and i was wondering, how long will take for these side effects to wear off?
