Hi, Thanks for posting in HCM. I understand your concern. What problem you are describing is more of psychological than physical one. It appears that you are getting too much excited about the phenomenon. Kindly relax as these are natural acts one should perform in life. Masturbation is a healthy physiological phenomenon and does not cause any harm to the body or sex life or fertility. However, it should be spaced well and should not be overdone. You can build you confidence by practising behavioural therapy like pause and squeeze technique. Include in your diet - almonds, banana, pineapple, saffron, cardamom, figs, honey and pumpkin, which are known to increase the blood flow to the penis and help to initiate and sustain erection. Also, doing meditation would help you to overcome anxiety and keep your mind calm and healthy. Over a period of time, your confidence should improve and you should be able to sustain better. Hope the information provided would be helpful. All the best.
