Also known as Cupid's Arm, Valentine's Disease is a malformation of the penis, in which the head is shaped much like a heart. While there can be complications in urination and ejaculation, many men are proud of their misshapen tips, as some women are inclined to provide oral sex while wearing red lipstick in order to shade the growth. This act is known as a Valentine's Kiss.

When having vaginal intercourse, the vagina is then known as a Heart-shaped Box.
