Dear service user, Thanks for writing to HCM. I understand your concern. This is called performance anxiety. As you said it is psychological nature. Situational reasons like fatigue tension or own pressure to perform rather to enjoy is very common. This is likely in you. This occurs especially in newly married couples when one is highly concerned about own performance and desperate to satisfy’. When individuals are highly concerned about their performance and unfortunately focus on their penis for performance; it leads to erectile failure or weak erections. First erectile failure due to any reason leads one to be worried about next sexual encounter. One focuses constantly on how do i perform . This leads to anxiety and difficulty in erection in subsequent sexual activities. One’s anxiety goes on increasing with every ‘failure’. 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. Wish you good health.
