The pelvic thrust is used during copulation by many species of mammals, [1] [2] [3] including humans, [4] or for other sexual activities (such as non-penetrative sex). In 2007, German scientists noted that female monkeys could increase the vigor and number of pelvic thrusts made by the male by shouting during intercourse . [ 5 ]

In post-copulatory mate-guarding males are trying to prevent other males from mating with the female that they have mated with already. For example, male millipedes in Costa Rica will ride on the back of their mate letting the other males know that she's taken.
