Hello doctor I am having 3 questions please answer to that 1.If I take suhagra tablet for few times when participated in sexual intercourse. Now if I stop taking suhagra tablet does erection happens when I participated in sex without taking tablet. (indirectly the question is if we have a habit of taking tablet does erection occurs when we don't use it) 2.As I heard that these tablets having more side effects. My question is these side effects will effect temporary or permanent for rarely using of this tablet 3.I want to use this once in 3-4 months. Will you suggest that rarely using this also effect erection problem when I will not use tablet.(which means making habit of taking tablet. Is it compulsory to take when doing sex or if we will not take tablet also erection happens?)
