Falling Asleep Right After Sex is Normal

It is normal to fall asleep right after sex. After intercourse, many men fall asleep. Such a reaction to intimacy often offends the partner, but it is completely natural and dictated by physiology. The reason is that orgasm triggers the release of a whole cocktail of endorphins and other substances. Once they enter the bloodstream, they cause drowsiness in a person. Moreover, women can also 'fall into a deep sleep' under the influence of these substances.
