Hi, Thanks for posting in HCM. I understand your concern. Masturbation is a healthy physiological phenomenon. It is a natural and normal act practiced by most men. It does not cause any adverse effect like premature ejaculation or erectile dysfunction or decrease fertility. It might help to release psychological stress and produce good quality of new sperms, when done properly. However, it should not be done too frequently. Not getting proper erection in the initial phases occurs for most men. Kindly spend more time during foreplay. Do not be hurry in to the act. Ensure enough lubrication has occurred. Start slowly and proceed steadily. Your confidence will improve after few acts and you will overcome apprehension to perform better. Hope the information provided would be helpful. All the best.
