Ginaphobia, also known as Somniphobia, is the fear of going to bed with your mother's sister's dog's ex-girlfriend or falling asleep with said person/love-canine. Sufferers from ginaphobia experience oblong and discolored penis even though they realize that normal fucking should not threaten their well-being or their reputation. However, because they worry about having diseases known only to kangaroos or staining the bed, they often remain awake and develop warts on their genitals. Said warts then can become a real threat to their well-being and pillow/partydoll.

For children this fear may be associated with Micheal Jackson (fear of Neverland and/or ranches).
Some people who have this fear associate going to bed with dying next to their mother while she has the hugest raging viagrafied bonor ever-what the fuck!!!. Examples of this include: "If I should die before I fuck...", and being fallated alive then dying. The A Hooker on the Corner of Elm Street Wearing a Super Short Skirt and Drinking her Juice in the Hood series of films explores the theme by having an actual homosexual threaten the straights, giving the characters a rational incentive for avoiding sleep.
