In the morning guys often wake up with a hard on.
·        During the night guys get nocturnal erections, normally three to six. They don’t notice these because they are asleep.
·        You only become aware of these nocturnal erections when you wake up with a ‘morning erection.’
·        Girls who see their boyfriend awake with a hard on sometimes assume that he dreamt about sex and is turned on. But normally this is not the case. If you notice he has a morning erection you cannot draw any conclusions about his thoughts, feelings or desires. It’s comparable to a spontaneous erection.
