Hi,
If you are unable achieve an erection following stimulation, you would have to consider that you have erectile dysfunction (Impotence).
ED can present at any time in the sexually mature individual, though the incidence increases with age.
If you are able to attain an erection and are able to masturbate, you are not impotent.
Masturbation is not unhealthy if it is compatible with the capacity of the prostate gland to produce seminal fluid. If excessive masturbation is indulged in, the prostate gland may become irritated and cause prostatitis.
Ensure that your fluid intake is high and you avoid prostate irritants, such as caffeine and alcohol, if you have indulged in excessive masturbation.
Do keep us posted on your doubts and progress.
yes, masterbating every day is not good for your health. id suggest 3 times a week maximum.. and you'd me quite safe from prostate infections.
