Your imagination is the single, most potent engine driving sexual desire. Tap into your imagination and you’ve turned on nature’s built-in aphrodisiac. Fantasies are what keep sex fizzy when your sex life – or your partner – goes temporarily pear-shaped. They’re what can make sex with someone we’ve slept with hundreds of times seem not only remotely appealing but exciting. One of the quickest ways to arouse yourself is to fantasize. Even better, fantasies are a form of foreplay we can access in an instant – anywhere, any time – because we carry them with us always.
Some fantasies are fleeting. Others start off small then develop over time into rich, complex formats. Often they’ll start the same or feature the same characters but have different endings, designed to suit the mood we’re in. They generally last as long as it takes us to orgasm and we become adept at timing them so the climax happens when we do. Just like sexual positions, most of us have three or four favorite fantasies we return to time and time again.
