Those fluids may be vaginal secretions from women when they are sexually excited, which have a lubricating effect. In addition, there may be a small amount of secretion from the bulbourethral glands. The bulbourethral glands in the man&39;s body will secrete a small amount of fluid when he is sexually excited. It has the effect of neutralizing the acidity of the urethra, so that sperm can pass smoothly through the urethra during ejaculation. Although this secretion is different from semen, it also contains a small amount of sperm, which is enough to make a woman pregnant. Ejaculation outside the body is by no means a reliable contraceptive method. If you choose to have sex in the future, you need to think carefully beforehand and take adequate precautions to prevent accidental pregnancy and sexually transmitted diseases.
