Thank you for asking. One minute is a very less time to ejaculate. Yes, there is  risk for premature ejaculation problem in future. I would suggest you to learn a technique of guided masturbation. It will help you out to control the ejaculation while masturbation and subsequently help you in intercourse as well. I would need to know more about the pattern of masturbation and also if there is associated pornography use. After a detailed evaluation I can be able to suggest you a specific management and instructions.
