Hi, Thanks for posting in HCM. I understand your concern. Based on your description it appears that your condition to achieve proper erection is more of psychological than physical illness. This is caused mainly due to lack of confidence and anxiousness. It might be caused due to intake of meth and hence it would be advisable for you to stop using it for your betterment. You can overcome problems with getting proper erection by doing the following: 1. Practice stop and squeeze technique regularly. 2. Perform pelvic floor strengthening exercises. 3. Include in your diet almonds, dates, milk, saffron, papaya, green leafy vegetables and pulses, which would help to provide adequate blood supply to the penis to sustain erection. 4. Take Tablet.Tadalafil half an hour before intercourse, only when necessary. 5. Practice meditation regularly, which will help you to overcome anxiety and improve your confidence gradually. Hope the information provided would be helpful. All the best.
