The symptoms: During intercourse you want to look like an A-list starlet in a choreographed Hollywood sex scene. You feel conscious of your facial expressions and you find yourself acting out moves you've seen on TV rather than following the natural rhythm of your body. If that isn't enough to think about, the idea that you could fart at any moment completely horrifies you. Scarlet magazine's editor, Sarah Hedley says: 'From an audience point of view, raw sexual energy is far more erotic to watch than Hollywood's Meg Ryan-style climaxes, and as a general rule if you spend more time wondering about whether you look sexy rather than whether you actually feel sexy, you're definitely doing something wrong.
'To see what you're missing out on, try having sex with your man in complete darkness with appropriate background music to cloak both sounds and sights. Focus every ounce of your attention on the feelings in your erogenous zones. Concentrate on how great your clitoris feels with each thrust, linger on the delicious sensation in your nipples as he licks your breasts, contort your face, breathing deeply in and out with no regard for the world outside of your body and its responses. That is what good sex feels like, and if you practise it often enough you'll soon be able to recreate it with the lights on.'
