If they’re not whinging at us for going fishing too often, thenthey’re moaning and groaning in the bedroom as they fake anorgasm.

“Oh darling, that was wonderful,” she coos, fluttering hereyelashes at you. “You don’t really want to go fishing tomorrow doyou?”

Oh, those all too familiar words.

Can you imagine this: “Darling, do you really want to go chasingflies tomorrow?” Followed by an ecstatic groan and a fluttering ofthe pectorals as the seductive female brown trout tries to trick herpartner into a premature ejaculation.

It’s not so far from the truth you know, for Erik Petersson andTorbjörn Järvi of Sweden’s National Board of Fisheriesstudied brown trout in an aquarium and discovered that the female ofthe species faked orgasms in 69 out of 117 couplings.

The two biologists say that the idea is to trick potentialpartners into premature ejaculation with the idea of helping thefemales to avoid mating with undesirable males or attract morepartners. As brown trout pair up to spawn both the male and femalequiver violently with their mouths open. Then, what normally happens,is that eggs from the female and the sperm from the male are releasedat the same time to enhance the chances of fertilisation.

Then the tricky bit starts as the female does what women do best,they fool the bloke into releasing his sperm.

“The females behave as if they should spawn,” says Järvi.”They trick the males into releasing their sperm”. And suggests thatmales take every opportunity to have an orgasm even when there is noguarantee of a successful fertilisation.

It does sound familiar.

They noticed that most females spawned with the male they’dtricked into premature ejaculation, and then they often spawned withsuperior males that had bigger fins and jaws.

And that sounds even more familiar.
