Hi, I Am Married Since 5 Years. Never Could Enjoy

Hi,
I am married since 5 years.
Never could enjoy intercourse more than 2-3 minutes.
Foreplay can not continue more than 5 minutes.
If she touch penis I ejaculate immediately.
We can't enjoy.
If I try to intercourse then ejaculate before going inside or just after going inside in 2-3 stroke.
Tried to make mind or not to get excited but does not work.
In 5 years relationship not enjoying SEX life increase frustration for both.
Please advise for cure.

Thanks
