What is precum

Precum can be compared to watering of the mouth that happens when hungry person smells aroma of delicious food being cooked and is about to be served. Watering of mouth is compared to precum because as in the hungry person on seeing his favorite sweets or candies there is watering in mouth so too on seeing erotic pictures or talking naughty sex talk or during foreplay.

Precum comes at the beginning of sex. Semen comes at the end of sex.

Precum is watery colorless slightly sticky fluid that oozes out of penis during sexual excitement. Precum is not semen. People often get scared due to the wrong belief that semen has come out.

Purpose of precum

Nature has designed the discharge of precum to act as lubricant. Pre-cum also acts as acid neutralizer. In both male and female watery discharge starts at the time of sexual arousal.

Why Precum

  • Sex means friction. What a smart way God has designed this lubricating fluid precum.
  • Acidity of urine is not suitable for sperms. Precum as though washes away and neutralizes this acidity. Precum also helps in neutralizing the acidity of vagina.
  • Precum has a role in coagulation of semen.

Names of precum

Precum is also called as pre ejaculatory fluid or pre ejaculate or pre seminal fluid or Cowper’s fluid.

Source of precum

Cowper’s gland (see in the picture above) secrete watery fluid. Bulbo urethral glands (Cowper’s glands), glands of littre release this watery fluid. Precum is lubricant as well as acid neutralizer. Preejaculatory fluid is also called precum or pre ejaculate. This is not semen.

Amount of Precum

Some men may not produce precum. Some men may produce up to 5 ml of precum. Typically the underwear gets a wet patch because of precum.

Pre-cum, HIV/STI and pregnancy

Precum has been found to contain HIV Human Immunodeficiency Virus that causes AIDS Acquired Immuno Deficiency Syndrome.
It was believed that precum also may contain sperms. Hence, it was said that contact of precum with vagina or nearby may cause pregnancy. However, there are some studies that show that precum does not contain sperms. Not only that, but the studies also show that withdrawl method or coitus interruptus of family planning is as effective as condom in preventing pregnancy.
If you have questions you can ask doctor.

QUESTION by Anil (name changed)
Respected Sir,

I m going to marry but problem is, i get ejaculate in very short time,

Aur ye baat mujhe andar hi andar tension de rahi hai,

why i ejaculate glue/water like material even on touching a female or seeing a pornographic clip.

But i m still addicted to sex..MUJHE LAGTA HAI JAISE MUJH MAE SEX BAHOOT HAI,

Please give ur suggestions

Hi Anil,
The glue like thing that comes out on sexual arousal is called ‘precum’. This is normal and a good sign that you are sexually aroused.
You are not yet married and you do not have sex regularly. When you occasionally have sex your sexual excitement is very high and you discharge quickly. When you have sex regularly it is like having the same food daily. Excitement level is lesser and you will be able to have satisfactory sexual life. In case of high excitement here is a useful tip for you. After the first discharge chat with her for a while or doze and take small nap. After some time begin teasing foreplay. Now you can do sexual intercourse again. In 2nd or 3rd consecutive sexual intercourse ejaculation is delayed. You can alternatively masturbate and then go for sexual intercourse.

Sex is not a bad thing. Don’t call it addiction. Sex is natural.

If you still have doubts or questions feel free to ASK DOCTOR.
