Hi doctor I'm suffering from erectile dysfunction from past 3yrs. I can't able to maintain erection at all and I'm not getting morning erection at all. While watching porn video I'm not getting any signal to active penis erection. Due to lack of masturbation done in past 5 times in a day. Recently I visited a sexologist they prescribed me Tentex Royal, Himalaya confido, and vamlift tablet but no result I found. And then I consult online on doc app 1 doctor told to take Nano Leo tablet for 1 month then it cure permanently. But I was getting doubt so I don't buy.  Then I consult another doctor in doc app He told that don't take any medicine bcoz you have not examined in online what is the problem you must go for urologist specialist he will examined and give right treatment. Is it true Please help me doctor for best result. And I want my hard erection back how previously I was having.
