What is the white fluid that comes out the first time?

The first流出 of white fluid may be semen, prostatic fluid, or bulbourethral gland secretion. Details are as follows:

1. Semen

The initial discharge of white fluid might result from sexual arousal. During male sexual excitement, a series of physiological responses occur, including penile erection, hardening of the glans penis, and congestion of tissues around the glans. These physiological changes stimulate organs such as the prostate and seminal vesicles to secrete semen. When sexual arousal reaches a certain level, semen is expelled through the urethral opening—this is known as ejaculation. Therefore, the first discharge of white fluid could be a normal physiological response caused by sexual excitement.

2. Prostatic Fluid

The first流出 of white fluid is often referred to as pre-ejaculate, because during male sexual arousal, prostatic fluid is released before actual ejaculation occurs. This typically happens in the early stages of sexual activity or masturbation, when prostatic fluid exits through the urethral opening, appearing as a white liquid.

3. Bulbourethral Gland Secretion

Bulbourethral gland secretion is a fluid produced by the bulbourethral glands, containing various components such as proteins and phospholipids. During male sexual arousal, this fluid is discharged, usually either just before or simultaneously with ejaculation.

It is recommended to maintain good personal hygiene in the genital area, keeping it dry and clean to prevent possible infections.
