Dear Welcome to HCM We understand your concerns I went through your details. Please understand masturbation is never the cause of your present problem. Masturbation is healthy, normal and natural. Delayed ejaculation (DE) is a common medical condition. Also called “impaired ejaculation,” this condition occurs when it takes a prolonged period of sexual stimulation for a man to ejaculate. In some cases, ejaculation cannot be achieved at all. While this condition does not pose any serious medical risks, it can be a source of stress and may create problems in your sex life and personal relationships. You should consult an urologist to determine the basic facts regarding your DE. There could be many factors like damage to the nerves in your spine or pelvis, certain prostate surgeries that cause nerve damage, heart disease that affects blood pressure to the pelvic region, infections, especially prostate or urinary infections, neuropathy (nerve damage) or stroke low thyroid hormone, low testosterone levels, birth defects that impair the ejaculation process etc Once the urologist determine the cause of your problem, the treatment starts and cure is sure.
