Have rutting and heat cycles, pheromonal attraction between Alphas and Omegas, Omegas, penises with knots (used to “knot”, or tie, the partner to an Alpha during copulation, an action known as “knotting”), scent marking, imprinting, breeding, mating rites, pack structures and potentially permanent psychic bonds with a mate.
Omega (Ω): submissive and gentle, calm and a peacemaker, instinctual, responding to animalistic physiological stimuli. Male Omegas are often envisaged as being able to become pregnant via a uterus connected to the rectum, and Alphas can impregnate regardless of their main gender. To make penetration and impregnation easier, male Omegas often have self-lubricating anuses. Omegas often hide their smell using chemical pheromones so that they are not a victim of biological prejudices.
