Half of girls fantasise about someone else during sex

The lights might be off and your alcohol levels might be high — you’d like to think your partner only has eyes for you.

But a new survey reveals almost half of women and 42 per cent of men are fantasising about another person while having sex.

And 30 per cent of ladies and a quarter of blokes actually went through with it, having sex with a mate they’d previously daydreamed about.

What’s more, the survey conducted by sex toy company Lovehoney, showed 97 per cent of 18 to 25-year-olds were on board with the idea of sexual fantasies.

Following the kinky 50 Shades of Grey effect, a staggering 70 per cent admitted they’d thought about bondage, while 43 per cent had raunchy lecturer or teacher fantasies.

Twilight might have come out a few years ago but perhaps vampires had a lasting effect on our sex lives as 51 per cent liked the idea of biting.

Elsewhere in wild bedroom fantasies, three quarters admitted being into public sex, while 71 per cent had considered domination and submission.

And it turns out sex with the ex is more common than we thought, as a third of women and 42 per cent of men confessed to having a former flame on the mind.

Despite this, more than a third of both genders admitted it felt a bit like cheating.

A Lovehoney spokesperson said: “Lots of people do reminisce fondly about former lovers – it is perfectly harmless thing to do as long as you are not intent on living out that fantasy if you are with someone else.

“All Lovehoney research shows that sexual fantasies enhance couples’ sexual happiness and are a good thing.

“Sexual experimentation is to be encouraged because couples who are happy in bed tend to be happy in the rest of their lives.”
