What is flowing out without ejaculation?

Sexual life is not unfamiliar to adults, and they are not particularly shy about talking about sex. After all, everyone has experienced it and is very familiar with it. Take the male penis for example. Before the start of sexual life, before entering the vagina, some liquid will flow out. In most cases, it is transparent. Of course, this is not ejaculation. So, what is flowing out without ejaculation?

During sexual activity, when a man enters the arousal phase, that is, after the penis becomes erect, if sexual stimulation continues, a pair of bulbourethral glands located behind the urethra and the urethral glands distributed along the corpus cavernosum of the urethra will begin to secrete. The amount of secretion varies significantly from person to person, and generally only moistens the urethra and the external urethral opening. About 18% of people will have excessive secretion, so that the secretion will automatically seep out and drip from the external urethral opening of the penis. This secretion is clear and transparent in appearance, and has a certain viscosity. People who do not know the truth often mistake it for semen. In fact, it is not real semen and generally does not contain sperm.

The secretion of fluid from the bulbourethral glands and urethral glands during sexual arousal in men has no clear physiological function. It is speculated that it may be a preparatory activity before ejaculation, which has the effect of neutralizing and cleaning the residual urine in the urethra. Otherwise, some metabolites in the urine will have a harmful effect on the sperm that is subsequently ejaculated. In addition, the urethral secretion can also lubricate the glans penis and provide some help for the penis to be inserted into the vagina.

However, it should be noted that sometimes a small amount of sperm may be mixed into the secretions of the bulbourethral glands or urethral glands. Even if it is only a very individual sperm, it may cause the woman to become pregnant if no contraceptive measures are taken before sexual intercourse.
