Suggest Treatment For Erectile Dysfunction

I am 32 years old. Married 3 years back & got a baby boy last year november. Problem: My pennis is not erecting well & not becoming hard to have sex with my wife. I see lot of porn movies & do the masturbation(Hasthaprayogam) once in a day (2011 to till now). I am thinking, this could be one of the reasons why this problem came to me. I am trying to control not to do any masturbation but, sometimes I am unable to stop it and doing it. After my marriage, when I do sex with my wife, my pennis erects but, it will stay for only less time & immediately go back to normal state. I did the masturbation s & somehow did inserted my pennis to my wife s vagina & got a kid. Now a days, I am not able to do sex with my wife & my pennis is not erecting if I go to her. I don t know the reason because of over masturbation or some other reason. I sleep late around 12-30 or 1-00 AM. But, if I watch porn movies and do masturbate, that would go fine. I feel good. My pennis comes straight (not too much) & able to do masturbate and release sperm. I dont know what to do to resolve this problem. I am stopping masturbation going forward (watching pron videos), will it help me in my sex life? I want to participate sex with my wife happily. She knows about this problem & feeling sad. She used to ask me when we will have sex repeatedly. I am not doing any sex with her from last year 2015, June to till now. Please guide me any solution so that I can recover & do healthy sex with my wife without any issue. I think, you might have understood my problem now from the above explanation. I request you, please guide me some solution for this problem. Please do the needful. Thanks.
