When women of childbearing age have sex, vaginal secretions will increase, mainly for the following reasons: First, sex will lead to sexual excitement and temporary changes in hormone levels in the body, which will increase cervical secretions, so vaginal secretions will also increase when having intercourse. The second is that during intercourse, the vestibular gland fluid will be ejected in a jet-like state, so it will cause the secretion to be as much as water, which mainly plays the role of lubrication, which is a normal phenomenon. It is advisable to pay attention to hygiene before and after intercourse, and it is also advisable to do vulva washing after intercourse to ensure local cleanliness and avoid pathogenic infections.
