I'm not big on very sweet, either, but I do like chocolate. I like that it is bitter and sweet in the same bite. However, I don't like the chocolate that is overly sweet.
On the other hand, I don't like coffee. I know of some people who love the smell of coffee, but hate the taste. I don't like either. To me it smells like a skunk. My oldest daughter is the same way as I am (even the skunk smell), but my other three children and my husband are not. They are all coffee lovers (fanatics). My other two daughters will drink iced coffees and fancy coffee drinks, my husband and son will only drink hot coffee black.
If everyone loved only the same things, this would be a boring world and there would be no creativity.
