Similar to other anthropomorphic species; Anthro Bears also have a ‘Heat Cycle.’ The bears usually begin their heat cycle just before hibernation.
Once in heat, the bear will find themselves increasingly horny and drawn to the scent of other bears.
Once sufficiently safe and in the proximity of others, they find themselves drawn to masturbate & pleasure themselves. The scent of their fluids & sounds of their activities is usually enough to attract a mate.
Once a pair have mated, they usually retreat to a secluded cave or burrow to ride out their hibernation together.
