Your last sexual intercourse was likely a result of a combination of physical and psychological arousal. The physical arousal may have been caused by external stimuli, such as visual stimulation or physical touch. Alternatively, it may have been internally generated, such as from sexual fantasies or daydreams. The psychological arousal may have been caused by positive emotions, such as excitement or happiness, or by negative emotions, such as anger or fear.
Regardless of the cause, the sexual intercourse itself is typically a short, intense burst of pleasure followed by a period of relaxation. The intensity of the sexual intercourse can vary from person to person, and from one experience to the next. For some, ansexual intercourse may feel like a gentle wave, while for others it may be more like an avalanche or a volcano.
