A CHIMP has been caught on camera masturbating with a plastic bottle in what sceintists believe is the first time a wild ape has used a man-made sex toy. Araali, a male chimpanzee in Bulindi, Uganda, was spotted putting the discarded bottle on his manhood and “thrusting” into it, a scientific research paper says.

It continued: “‘At times he showed a relaxed open-mouth expression or a ‘play face.'” According to the academics – from Oxford Brookes University, University of Exeter, and Utrecht University – at one point the chimp’s willy fell out of bottle before he “reinserted” it. “For the remaining eight seconds of the recording, Araali sat with a play face, apparently with his penis still inside the bottle,” the paper says.

Masturbation is more common in captive chimps due to stress or lack of mates – however researchers say they have seen wild apes pleasure themselves while “fumbling” with their private parts. Male chimps have been seen using fruit or smooth stones to masturbate before but this is the first time a man-made object has been used. The experts believe Araali used the bottle because he lives near humans and is familiar with man-made objects where as most apes would show no interest in them. Speaking of the chimp’s motives, the paper says: “The physical properties of the open bottle presumably elicited Araali’s autoerotic response, suggesting he recognised its suitability for that purpose. “Considering he exhibited a play face while ‘copulating’ with the bottle indicates his masturbatory behaviour was “pleasurable” or “fun.”‘ The paper continues: “This unusual observation raises questions about the function of masturbation in male chimpanzees. “It contributes to an understanding of the range in behavioural responses of wild apes to novel objects.” We pay for your stories!
