Giraffe guys that get down, albatross ladies in love and beetles that just can't get enough sexy time ... If you thought monogamous guy-girl relationships were nature's norm, you're in for a serious shock or two - turns out you can find homosexual twosomes (and threesomes ... and foursomes) all over the animal kingdom!

Sex sells ... all over the animal kingdom. Females from numerous species use prostitution to get what they want – and males are eager to pay up. Penguins pay for lurve with rocks, beetles offer nuptial gifts and chimps may bargain with a fruit or two … for many animals, sex is all about the right transaction.

Humans are not the only animals who sometimes take things into their own hands when it comes to sex -- countless other species do it too. From crickets & their 'autonomous sperm ejections', to sneaky masturbating iguanas & some squirrel genital grooming, going solo can have some surprising evolutionary benefits.

This time on Wild Sex, we're getting down & dirty. Really dirty. Find out why porcupine sex involves golden showers, why hippos use their tails like high-powered poo propellers & why giraffe males must be urine-swilling connoisseurs if they want to hook up...

Monogamy begone! This week, we're looking at animal species that enjoy the biological benefits of multiple mates. Whether it's the writhing orgies of garter snakes or the whipped-up debauchery of the foam nest frog, sometimes a little promiscuity goes a long way.

What you're about to see is going to make 'Fifty Shades of Grey' seem like Cinderella. Don't believe us? Well, get ready for genitals that become weapons, a side order of cannibalism, a few sexual stab wounds and maybe a round of penis fencing … It's BDSM in the animal kingdom.

This week of Wild Sex, find out why rabbits deserve their frisky reputation, why tiger sex is a prickly affair and why you never (ever!) want to be anywhere near a copulating camel. And to end off, some tips on technique from a crab!

If you want to get lucky with the ladies you'd better learn to share. Just ask a few apes. In this episode of Wild Sex, female orangutans put potential partners to the test by shamelessly swiping their food -- and only the most generous males will get the girl.

Anti-aphrodisiacs, penis sacrifice, vaginal plugging ... when it comes to ensuring their own reproductive success, males from these animal species are prepared to go to extremes to keep their mates on the straight and narrow.

Male dominance? Not here. In elephant and hyena societies, it's the females that call the shots. And when it comes to sex, nobody's getting any unless the lady retracts her pseudo-penis!
