Hi, Thanks for posting in HCM. I understand your concern. Masturbation is a medically healthy and psychologically normal habit. Doing it regularly is not known to have any adverse effect on health such as hormonal imbalance, causing weakness, decreasing sexual ability or performance and affecting fertility. What you are suffering from is more of psychological problem than physical illness. Most men happen to fail during first few times while having intercourse due to apprehension and lack of confidence. Kindly practice pause and squeeze technique as part of behavioral therapy regularly. Consume diet containing milk, almonds, dates, figs, honey and papaya, which would help to improve blood supply to penis and sustain proper erection. Practice meditation regularly to keep your mind calm and healthy. You can take Tablet.Tadalafil to sustain erection when necessary and apply local anesthetic cream to decrease sensitivity. Gradually, you should be able to sustain erection for a longer duration and improve in your performance. Hope the information provided would be helpful. All the best.
