* Following [[Reproductive_Behaviour_-_Copulatory_Behaviour_-_Anatomy_%26_Physiology#Ejaculation|ejaculation]]
* Following [[Reproductive_Behaviour_-_Copulatory_Behaviour_-_Anatomy_%26_Physiology#Ejaculation|ejaculation]], all males experience a refractory period (commonly referred to as 'sexual exhaustion') before a second ejaculation can occur.
* Length of refractory period depends on several factors:
** Degree of sexual rest prior to copulation
** Age of male
** Degree of female novelty
** Number of previous ejaculations
* Normal for a male to copulate repeatedly with the same female.
** Stallion will breed a mare in heat 5-10 times during one estrus period.
** Rams remate with the same ewe 4-5 times.
** Bulls remate with the same cow repeatedly.
** Boars normally serve sows several times over a period of 1-2 days.
* During the refractory period, further stimuli will not cause immediate responsiveness or motivation under a given set of stimulus conditions.
* Restimulation may occur after the refractory period.
* Large variation in behavioural reserves (behavioural capacity/'''libido''') among species.
* Large variation in libido within species.
** Governed by genetic and environmental factors.
