Dear service user, Thanks for writing. I understand your concern. 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. Inadequate sleep does affect the sexual performance. 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 because the mind gets diverted while sex. For constant erection, there should be continuous erotic thoughts , feelings of joy of sex. If mind is diverted to focus on erection , you will lose erection. Just enjoy kindling during sex without bothering about quality of erection. Practice it regularly. You may have counseling with sex therapist or psychiatrist if the problem persists despite of above practice for next 20 days. Diastolic pressure cannot be 7 mm of Hg. It must be error. Relax. 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.
