Hi, Thanks for posting in HCM. I understand your concern. What problems you are facing with reference to premature ejaculation and erectile dysfunction is more of psychological problem than physical. It is not caused due to masturbation, which is a normal physiological phenomenon and is healthy when practiced within limits. To overcome erectile dysfunction, you can use Tablet. Tadalafil 30 minutes before the act to achieve good erection. For premature ejaculation, you need to practice behavioral technique like pause and squeeze technique along with use of local anaesthetic spray to decrease sensation. Slowly, over a period of time, you would gain confidence and can overcome the problem. You can also practice meditation to keep your mind calm and spend more time during foreplay to increase your confidence. Hope the information provided would be helpful. All the best.
