Wish I had your 'problem', OP
That said, even though it's not a big deal if you don't drink beer (you'll just have to deal with your friends' ribbing!), the wonderful world of beer can truly be life enriching.
One of the ways of getting into beer is mixing it with coke - this actually has a name but I can't think of it. People do it a lot in Germany I think. Anyway, half coke/half beer tastes a lot sweeter, is less alcoholic and generally a lot more pleasant for the novice drinker.
Alternately, you could try mixed beers or beers that are generally a lot sweeter - after all, it appears the bitterness it what most people dislike. For instance, kriek beer is a subtype of a regionally brewed beer from Belgium prepared with cherries. Alternately, Belgian beer Palm is also significantly sweeter. Also weissbeers (whitebeers? Iunno translation) like Hoegaarden or Schneiderweize taste significantly different from what you'd normally expect from beer. Last but not least: a lot of special beers like double or tripel beers have added sugar for higher alcohol content and flavor. They can be very smooth and tasty. But be careful - they'll fuck you up harder than you'd expect.
I'm not sure where you're from, but I think it's a pretty safe bet that you're from the States, in which case I can't really recommend anything specific since I don't quite know what beers are popular there. I do know Budweiser is fairly popular, but that it tastes like ass. But I also know Hoegaarden is getting more and more popular abroad, so if I'd have to recommend one 'novice' beer it'd be that one. It also has a rosé (= with cherries) version, so that's good too.
Lastly and most importantly: make sure it's poured properly. Nothing ruins the joy of beer more than shitty serving. The beer has to be cold, and ideally, the glass too. The glass has to be clean - any fatty residue and it'll transform any beer into stale piss in seconds. If you get it from a draft, smell it first - if it smells 'off', that means bacteria and that they never clean their taps and you need to get the hell out of there, because that beer's ruined. It has to be drafted in a single pour. And for the love of god don't drink from a pitcher, it'll be flat in minutes.
TL;DR Try out different beers, and don't let anyone sell you sub-par beer

Most importantly: enjoy!
