Lady Gaga is SLAMMED for posting ad for migraine drug as she teams up with pharmaceutical giant Pfizer: 'You really are an embarrassing sellout'Īmy Schumer's Netflix special that excoriates Hilaria Baldwin includes joke about Alex Baldwin's Rust shooting that Oscars banned her from making The average length of an erect gorilla penis is 1.25inches, compared to a human's five inches. Compared to a male human, gorillas have very small penises and testicles.

Yet despite their size - adult gorillas can weigh up to 374lbs - male gorillas are not known to be well endowed. It's therefore not uncommon to hear of a gorilla mating with one of their half-siblings. She also noted this competitive behavior could explain how humans evolved into a mostly monogamous species.īut gorillas remain a polygamous species in the animal kingdom and dominant males will often have sex with multiple females. 'It seems to us that mating is another tactic that females use to compete with each other – in this case to gain favor with another male,' primatologist Diane Doran-Sheehy said. Research has also proven that the great apes can have an orgasm from intercourse, which female gorillas have been known to use as a tactic to take down their enemies. 'The range of non-conceptive sex acts include genital-to-genital rubbing, oral sex, mutual masturbation and even the seemingly human-exclusive practice of French kissing,' according to primatologist Frans de Waal, co-author of Bonobo: The Forgotten Ape. In fact, gorillas are one of the only other species to have sex in the missionary position with partners of either the same or opposite sex. Humans and gorillas have 98 per cent of the same DNA and thus it's not so shocking that our closest living relatives aren't too different from us when it comes to having sex.
