“It started as a fantasy, just thinking my wife might sleep with other men.”

But for Will Cornudo*, that fantasy has become a reality.

Cornudo is a cuckold: he enjoys his wife sleeping with other men.

He and his wife had been married for 16 years before he told her of his fantasy: “I was worried she’d be horrified but the thought wouldn’t go away,” he told The Independent. After a couple of days, she agreed to give it a try and the couple haven’t looked back.

“We’ve been completely happy ever since, we both feel we can be completely free,” Cornudo says.

For the past three and a half years, Mrs Cornudo has been using adult dating sites to meet men - she doesn’t ask her husband if she can go on a date, she tells him.

The first time it happened, Cornudo met her wife’s new lover both before the date and when they returned before going up to the bedroom - Cornudo listened in from another room. “It was one of the most erotic things i’ve ever experienced. Knowing someone was in the next room with my wife was even more exciting than I’d imagined,” he explains.

At about 3am, his wife came back to him, expecting her husband to be fast asleep. “But I was wide awake,” says Cornudo, “She could see how proud I was of her and how happy it had made me.”

For it is excitement that Cornudo feels, not jealousy: “If she sees one particular boyfriend a lot in a little while, I get a bit irritable, but not jealous.”

And although she was hesitant at first, Mrs Cornudo now loves her lifestyle, being able to do whatever she wants like a single woman but with the security of her marriage and a husband who loves her.

The cuckolding lifestyle allows Mrs Cornudo to feel powerful and free above anything else. “She hasn’t got to answer to anyone. We agreed that she can do what she wants as long as she tells me about it,” Cornudo explains.

For Cornudo, the ideal scenario is watching his wife in bed with another man, but that only happens when the lover allows it.

Despite Mrs Cornudo’s extra-marital relations, the couple say both their sex-life and marriage are better than ever since Cornudo became a cuckold.

“Our marriage now has complete trust - we can talk about anything at all, perfectly openly,” Cornudo explains.

Despite their openness with each other, the couple haven’t told any of their friends or family about their lifestyle.

Cornudo, who has written a book, Cuckold At The Keyhole: My Wife's Sexual Adventures, doesn’t see any other women and struggles to explain why he likes being a cuckold: “I don’t know why it excites me, it might be a submissive thing - maybe it’s the idea of another man taking what’s mine,” he suggests.

“The thought of it before it ever happened excited me and it’s even better than I thought it would be.”
