Try things like sharing the taste of a good wine between you.

Also cognac is a great warm up. Used as a dribble on the clitoris and let it run into the vulva slightly, the delayed reaction of a heating up sensation will send you crazy. But don't use anything effervescent, like champagne, it is like being attacked by a thousand needles at once.

Ice Cream shared or on the labial area is another amazing sensation, again only creamy ones , don't use anything like choc-chip. We made a real mess trying that, lol.
