Thank you for asking. I can understand the distress you are through. It could be a problem of premature ejaculation. The time to ejaculation is very short. Multiple factors such as stress anxiety, masturbation habit, pornography use, lifestyle associated risk factors, etc needs to be explored in details. These have an important implications on one's sex life. A detailed information regarding these is needed. If needed suitable medication and instructions can help you overcome this problem. Loss of sex drive, low confidence, performance anxiety, depression can be secondary to it. With suitable medication(if required)  and instructions, the ejaculation duration can be improved.
