Sexual intercourse or intercourse is a tool or means of reproduction (reproduction) in all mammalian species. Unlike other species, intercourse in humans can take place at any time of the menstrual cycle, whether or not it is subsequently produced. The physiological response to sexual stimulation is similar in males and females. It includes the following stages: excitement, stability and departure.
The arousal stage in females includes increased vascular expansion, congestion in the clitoris, small and large cysts, and increased vaginal maturity. These changes are increased during the stabilization phase of sexual work, where further lubrication is due to secretions of the peritoneal glands.
In males, the penis is required to increase the length of the penis and its hardness. This results in a major vascular phenomenon, which is complemented by the expansion of the penis's arteries and the contraction of the penis, which results in a blood pressure pressure that causes the hardening of the penis and adjusts this process by means of unknown nervous and transient mechanisms. Via a sympathetic peer-to-peer fiber of the visceral visceral nerve. It has been suggested that the vascular ventricular peptide (VIP) may play a role as a possible neurotransmitter in this regard. Towards the arterial catheters and subject to the control of the adrenaline act of the alpha model and the lack of friendly reinforcement leads to the occurrence of the stump. Neural and psychological factors can affect the process of osmosis.
