Thank you for asking. I can understand the distress you are through. I suspect a problem for premature ejaculation. A condition in which the time for ejaculation is 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.
