Animals are also addicted to 'relationships' by mouth

Scientists have observed that a pair of brown bears kept in Croatia often "have sex" with their mouth for years. The discovery has shown an unprecedented mating preference in this huge creature.

According to a research report published in Zoo Biology, two unrelated male bears were orphaned shortly after birth in 2003 and kept in captivity at the Kuterevo wildlife sanctuary. Croatia. With 116 hours of observation over a period of 6 consecutive years, the team led by expert Agnieszka Sergiel of the Polish Academy of Sciences, witnessed 28 times the aforementioned male bear stimulated the sexual organs of the partner how to suck and lick

Scientists found that the larger bear is often the "served" object. Many times, this bear seems to have "peaked" thanks to sexual stimulation for only a few minutes. The evidence for this is the muscle contraction as well as the secretions on the muzzle of the "serving" bear. When the "briefing" is complete, the person who is satisfied often uses the hind legs to push the "servant" away or turn away.

Scientists call their study "the first observations of penis stimulation by sucking / licking, long-term repetition of brown bears kept in appropriate conditions after being orphan". In the past, they had observed bears in their "sex" captivity or self-stimulating penis combined with masturbation, but they were all considered unusual incidents in which the children Bears may be living in substandard conditions.

Sexual reparation seems to be the motive for many animals to participate in non-reproductive "relationship" behaviors. For example, the jaguar or sucking lion, licking the sex organ of a partner like a courting ritual. The famous eccentric bonono monkeys also do this to ease tensions in the community. Meanwhile, females of Chinese fruit bats often "have sex" with their mouths to make males extend their "love" time.

Two brown bears in Croatia can "relate" orally to sexual satisfaction. However, researchers are confused by the fact that the bear who plays the role of "servant" is always the instigator of this kind of behavior.

The team noted that both bears were very small when forced to stop breastfeeding - acting not only to supply milk to them but also to bind and reassure them for at least the first year of life. Two orphan bears have been reported to suck their own claws, ears or other body parts or cousins ​​to replace the nipple. Therefore, experts conjecture, for the " bear " bear, sucking and licking the bear's penis may be the remains of immature behavior.

Still, there are still a few unanswered mysteries. For example, researchers do not know why only one of two bears takes care of "serving" by mouth or why it is maintained for a long time. They acknowledge that this behavior may simply be the bizarre consequence of captive life.
