The Book Ends Sex Position is a variant of the common Missionary - one of the first and most popular positions people try. The simplicity and the high level of intimacy experienced are somewhat offset by the poor angle for penetration. To get into the position, the giver and receiver simply kneel down facing each other, with the receiver holding their legs slightly open (to adjust for relative height the giver will probably need to spread their knees also). This can be a good position for intimate genital contact without penetration (known as Dry Humping).
