Hi Man deep, Do not worry. It will all be ok. I would advise you to decrease masturbation to once or twice a week at max. Also, the problem of not achieving full erection is due to performance anxiety. You are thinking too much and putting lot of pressure on yourself for the same. Try and relax as there is nothing wrong with you. Let me know if any further advice is needed we are there to help you through this. Take care. Chat Doctor.
