Dear service user, Thank you for writing to Healthcaremagic. I can understand your concerns about erectile dysfunction. Let me tell you that both partner s satisfaction which is important rather than duration. Long duration sex doesn t mean satisfaction. This varies from individual to individual. Discuss this with your partner first. Understand REALISTIC needs of yours first. Masturbation does not cause erectile dysfunction or impotency. It is rampant myth. It’s the belief about semen loss which leads to anxiety which in turn causes erectile dysfunction. Re vital does not help. It is just like placebo. Have regular balanced diet rich in fibers and green vegetables. An occasional episode of erectile failure due to functional or situational reasons like fatigue, tension or own pressure to perform rather to enjoy is very common. This diminishes arousal level and hence erection too. This seems in your case. This failure of erection makes one feel I should perform best and he tries to erect’. This in turn further leads to lack of erection. Just enjoy kindling and loving with touch in the way both of you feel comfortable, rather than focusing about your performance and pressure to satisfy her. What you need to do is to consult a psychiatrist well versed with psycho sexual therapies. He will definitely assist you to come out of this problem. Erectile dysfunction is very common, even in people younger than you. I hope this will help you. If you have additional questions or follow up questions then please feel free to write to us. I will be happy to answer your questions. Wish you good sexual health ahead.
