If you love coffees that possess fruity characteristics, I'd say go for African coffees. Just like Tanya's suggestion, Kenyan and Ethiopian coffees are best for people with preferences like you. These coffees are known fro their citrus, berry, and stone fruit tastes. In addition, brewing your coffee over ice will highlight the fruity notes even more.
Finally, if you're not into sugar or sweeteners, you can lean to beans that are medium-roasted or slightly dark. These beans usually develop a little sweetness from the roasting process.
