A dating company called 'Illicit Encounters' which - as its name perhaps suggests - arranges for married people to find other partners have surveyed a couple of thousand people to find out what turns men and women off whilst having sex with their partners.
Obviously, before we begin, sex can be awkward enough at the best of times. It's even worse if you aren't enjoying it as much as you could be.
Anyway, the company - basically Plenty of Fish for people who already caught one they don't like - has compiled a list of sexual dos and don'ts for both men and women. Here we go.
For men - tragically predictably - the biggest problem was that women (apparently) don't initiate sex often enough.
Inset your own joke about that, ladies.
64 per cent of men think that their partner should start things off, it would appear. Well, of the 2,000 people asked, anyhow.
Oh, and men also hate when women want to have sex in the dark, as well as faking an orgasm.
Surely if a woman feels like she has to fake an orgasm, that's hardly her fault. Perhaps paying a bit more attention might solve the problem for everyone concerned?
As for the women, who presumably also hate having to fake orgasms, their biggest turn off is men who skip foreplay. That sort of brings us back to the previous issue. If you don't put in the work, guys, you're not going to get anywhere.
Whilst we're here, another gripe reported by women is men who are selfish and just get themselves over with. Oh, and embarrassing and crude dirty talk.
I think we can all agree that shouldn't be allowed. As mentioned earlier, it's awkward enough.
Anyway, a spokesperson from Illicit Encounters called Jessica Leoni told The Mirror: "We find that what drives people to have an affair primarily is a lack sexual satisfaction at home.
"The key reason why both men and women are fed up with their partners is because they are not prepared to change and keep making these fundamental mistakes in the bedroom.
"If you avoid these simple mistakes there is less risk of your partner cheating.
"And you have a much better chance of pleasing a new lover if you do decide to cheat."
That's right - do what the company who organises cheating for people say, and no-one will ever cheat on you.
It's tough to argue with that logic, isn't it?
