does anybody knows what is prostate in males body..?

Here's a short section from my reference, which I suggest you read:

>>The prostate (from Greek προστάτης - prostates, literally "one who stands before", "protector", "guardian"[1]) is a compound tubuloalveolar exocrine gland of the male mammalian reproductive system. Women do not have a prostate gland, although women do have microscopic paraurethral Skene's glands connected to the distal third of the urethra in the prevaginal space that are homologous to the prostate<<

It is very near the ducts leading to the penis, and can cause urinary problems if it becomes enlarged, and prevents normal secretion of fluids from the kidneys.

There is a picture of it on my reference below.

It is an important gland in a man's body located inside the anus about 2-3 inches inside. It controls the man's sex fluids. Some men can poke their finger up inside the anus and feel it (a doctor for instance). Sex toys are often used to stimulate the prostate.

It is a gland which produces prostaglandin and other seminal fluids which are used to protect and prolong sperm while outside the male's body and inside the females body.

It is located about 2 inches inside the rectum towards the front of the body.
