Sex and spontaneity
It's a myth that sex is better when it's spontaneous. That holiday you've been looking forward to for the past six months - would it have been more enjoyable without any planning? Not necessarily. In fact, on the contrary, it might have been a disaster. Although a surprise sex session can be fantastic, planning builds anticipation. And anticipation builds arousal.
If you have kids or you work long hours, you'll probably need to schedule in time for sex. This means you can make sure you feel your sexiest by planning what to wear and taking a relaxing bath or shower. You can also spend days teasing each other with what you've got planned for when the time comes.
Taking turns
Another myth is that sex should be entirely mutual at all times. Apparently, you should caress one another at exactly the same moment, fuelling passion in perfect synch. But that's a bit like patting your head and rubbing your stomach. Yes, it's possible, but it means you can't concentrate properly on either activity. How can you focus your attention fully on giving pleasure at the same time as luxuriating in the sensation of being touched? It's not possible. Someone will miss out.
