The sound of men and women doing this.

The so-called bed-calling originally refers to a woman's charming hum in a low voice when she is at orgasm. Traditionally, men generally don't call the bed. If a man asks for sex, he must not be a serious person. With people's more and more comprehensive understanding of sexual knowledge, the problem of bed calling has been put on the table again.

Physiologically, women cry during sex for two reasons. First, when approaching or reaching orgasm, the oxygen content in the blood will decrease. At this time, women will fall into a state of mild hypoxia and present a series of so-called "climax symptoms" such as inattention, blurred vision and mild body spasm. When the oxygen content in the blood decreases, the carbon dioxide will increase relatively, so breathing will inevitably accelerate. When breathing is accelerated and disordered, it will naturally emit a low cry unique to orgasm.

The second reason is that when orgasm approaches, the "exciting substances" in women's brains will increase accordingly. At present, people's understanding of this "exciting substance" is still very limited, but it is already known that it can blur people's consciousness and relieve brain inhibition. This role will dilute women's reason and send out a cry that is unimaginable to them. Some women don't know if they made a sound afterwards. It can be seen that crying during sex is completely a spontaneous physiological phenomenon.
