Hello thanks for asking I can understand your problems. You have many abnormal psychosexual beliefs and I want to psychoeducate you that masturbation is not harmful to health. It doesnt cause decline in fertility or potency. It is considered as normal thing. So there is no reason to fear that masturbation has caused the problems. The problem of quick ejaculation (premature ejaculation) and erectile dysfunction need proper consultation by a psychiatrist. Medicines like sildenafil, tadalafil are very useful in erectile dysfunction. Dapoxetine as role in delaying ejaculation. These are prescription medicines so don t take the medicines without prescription. Herbal medicines like tantex royal and confido have good efficacy in premature ejaculation. Tantex forte is used in erectile dysfunction. These medicines are free of side effects and need no prescription. Just to reassure you masturbation is not the reason for poor erection, premature ejaculation. It is also not a cause of poor eyesight or weakness. These are abnormal beliefs and should be ignored. Exercise daily and keep yourself relaxed. Thanks, hope this helps you.
