Is it usual for semen to be watery? Lately I have noticed that my semen to be watery. Is this usual? It does not used to be that way, is this cause for concern? And I only masturbate once or twice a week. Thanks.Is it a symptom of prostatitis?

It is usual for the texture and appearance of young men's fluid to vary from time to time. Though, watery semen is generally a symptom of retrograde ejaculation in which the ejaculate goes backwards into the bladder. This is not hazardous, but abnormal liquefaction of semen might also be caused by prostate abnormalities, such as prostatitis.
