Men are such perverts that they even ejaculate in their sleep. There is a perfectly normal (i.e. non-perverted) biological explanation for this, but Fiction Land likes to pretend that it's always a result of an Erotic Dream and/or masturbation. Also, in Fiction Land, women never do this. (In Real Life, they do, but barring female ejaculation it's a lot harder for women to tell in the morning.) Truth in Television for both sexes, though this phenomenon is more the exception than the rule. A teenage boy's first nocturnal emission is often given the same treatment in The Talk as a teenage girl's first period.

Fancy, who left me with stains on my nightshirt and down-pressing belly.
