The '''space and freedom of interaction between the jack and the jenny''' seems to be a key factor in sexual stimulation. The time to first mount increases if the jenny is restrained (Henry ''et al'', 1991; Gastal ''et al'' ,1996). It is recommended that enough space be provided during in-hand mating of a jenny for the retreating behaviour to take place. | The '''space and freedom of interaction between the jack and the jenny''' seems to be a key factor in sexual stimulation.
