Hi,
I am 26 years old and got recently married. I have had sex before my marriage with many girl friends and never had any problem in erection eventhough sometimes i ejaculate soon.
Now after marriage, when i tried making love to my wife first time, i could not get erection at all. It was totally soft. I thought may be that is because I had masturbated earlier that day morning. After that, my wife had to travel abroad for her work. Now she is out of country and I am in United States. We have not had sex even once. After that, I am trying to get erection by stimulating my penis manually, but I am not finding it hard at all. I try masturbating. Even then erection is not hard and not for long time.

I am afraid that this is ED. My wife is coming back to join me in a month. I am too scared that if she comes to know of this problem of mine, what will happen to our relationship.

Also I have been masturbating everyday for past almost 12 to 13 years. I am not sure if that is the reason I am having ED at this age.

From what I read in internet, ED may be because of psychological or physical reasons.
I want to know how can I get tested if I am physically good enough (that is I am potent or impotent)?
What all tests I need to do?
And how much these could cost?(without insurance)
I read that there are some drugs like viagara,cialis,levitra..
which one is good and no sideeffects?
where can I get these?
how much these would cost?
Instead are there any other vitamins, supplements I can take to cure this? Like any specific fruits, vegetables, etc,...?

I am really worried.
I really appreciate anyone's help in providing me information.

Thanks
A
