Both beer and wine are a combination of sticking with it and experimenting and seeing what you like. It is a bit of an acquired taste - when I first tried wine it tasted absolutely disgusting and I wanted nothing to do with it. But if you stick with it you'll learn to like it. Also both beer and wine vary wildly from type to type. What type of beer did you try? Was it dark or light? Bitter or sweet? Syrupy? Flat? Carbonated? If it was a Hefe or a Blond or Witbier it was probably pretty wheaty and sweet. That type of beer doesn't do anything for me, personally. I like strong hoppy ales with a more bitter taste and maltier stouts that have more chocolatey and coffee notes. It's the same with wine. The obvious first point of differentation is whether you prefer reds or whites. Then within that - which types, even which regions. With both beer and wine it seems overwhelming at first, but the key to truly appreciating them on a level beyond "well it gets me drunk" is to experiment and see what you like. It's sadly common, particularly in the college scene to see people who say they don't like beer and then reveal that the only thing they've really tried is budweiser/pbr/maybe Heineken. When you start trying different things you realize how much variety there is to beer and you start centering on the flavor profiles that you prefer.
So if it was a wheat beer (like a Blue Moon or Fat Tire or the like - a light or yellowish color as opposed to the more golden-amber ales and dark stouts/porters) try an ale or a stout, if it's one of the latter, try the former. My personal experience is that wheaty beers tend to appeal most to people with no experience with beers. They're light and fruity - quite pleasant to drink which makes it more approachable than strong ales which tend to be bitter and overwhelming if you aren't used to the flavor. Stouts also work well - Guinness is often popular among people just getting into beer because it doesn't have a lot of carbonation and the flavors are rather mild. So yeah, just experiment, basically.
Also don't drink any Italian, Spanish, or French beer. It's mostly [feces].
