This is typical problem of premature ejaculation
. This is a common problem which many males are suffering from and because of the shame they feel, they don't want to discuss this. Although the intensity of this vary in different individuals.
This can be controlled and cured and requires some practicals methods along with your wife. Apart form that different medications are there which can be used to control and treat this condition.
I would suggest you to consult some psychologist
who deals in this aspect along with your wife and than according to your problem he/she can suggest both of you some methods to practice and some medications for use.
Another most important thing which very commonly lead to this type of problem is anxiety
associated with this type of situation and I would suggest you to try to control this as this is not your fault.
Thanks and take care.
