I am 22 years old. someday I suffer from premature ejaculation nd someday not. I do not masturbate (used to when I was 18) but for the last 3 years it may be around twice or thrice a month. I took da sutra 30 mg occasionally without any consultation from the sexologists and it works like a wonder. Yet there are no side effects except upset stomach. I just wanted to know the side effects if they are any and taking the tablets occasionally like thrice a month is fine or not?
