Hi, I read your query and can understand your concern. You seem to be suffering from premature ejaculation. Premature ejaculation is a treatable condition. I would suggest you to consult a psychiatrist. You can be treated with both medications as well as behaviour therapy sessions. Medications will include selective serotonin reuptake inhibitors like paroxetine on a daily basis or dapoxetine on as needed basis. Behavior therapy sessions will include sex education, relaxation training and teaching methods like squeeze technique and distraction for controlling ejaculation. It is highly recommended that you attend the sessions with your wife as that greatly enhances the chance of success. Hope this information was helpful. Best wishes.
