Double dicking is the action of two straight males taking a phallic object, placing it against their genitals and humping it, symbolizing the insertion of their penis into the partners penis. Because this is impossible, double dicking acts as a vessel for these sexual urges.

Double dicking is known as the ultimate male-male sexual experience.
