I am 39 yrs old and suffering from premature ejaculation from very begining. Sometimes before penetration and mostly after penetration I came within 8 to 9 stokes. Also when I indulge myself in sexual activities there comes a transparent lubricant out of my penis. I aroused very fast and also my erection is very hard. I hardly masturbate 2 to 3 times a month in early ages. but there was a problem of night fall.So kindly suggest me what to do and how to get rid of this situation.
