Only you can decide what will work for you. But probably the number one aphrodisiac is your own state of mind. If you feel sexy, you will be sexy. This will in turn, cause your partner to feel sexier. Think sexy thoughts or talk dirty to your partner.
Some couples like to use toys or play a game as foreplay.
You could call your partner at work during the day before your special evening and give him a preview of what's to come. Or put a love letter in his pocket or briefcase. Buy a sexy new outfit to wear or some lingerie, whatever makes you feel you look good. Get your hair done, or a manicure. You can even give each other a sensual massage.
