There's nothing safer to start with than using somebody else's words. If you're not ready to tell your partner your fantasies yourself, invest in an erotic book and try reading your lover a story at bedtime. We'd suggest getting a collection of stories like The Erotic Edge or Delta of Venus. Both of these books are proven classics, and if you read through the stories you'll probably find one that describes a fantasy you have! Try reading that one out loud and seeing how your partner responds. If your partner enjoys the erotic reading (before bedtime is always best!), let him or her take the book and pick out the next story he or she'd like to have read to them. You may even want to set the mood with some candles and wine to create a more seductive atmosphere. Eventually, you may even want to work up to writing your own erotica and reading it out loud to each other!
