Colorado.

Aren't there a handful of good craft breweries out in Colorado? If you can make time for it, give them a brief visit and ask, in person, about their less bitter offerings. They may be able to point you toward something that you'd really enjoy. Also, if you have any alcohol vendors that specialize primarily in beer, give that a try.

Honestly, if you can take a couple pictures at a supermarket/grocery store that has a large selection, you can look those up online and figure out which may best suit your needs, as well. Just do your best to steer clear of anything that says "IPA" on the bottle for now. Not all of them are very bitter, but if you're looking specifically for low-IBU, then you're not after an IPA right now.

Colorado.

Left Hand is from Colorado, I believe.

I like their Milk Stout quite a bit.

I'm a sissy. Any particular recommendations for light beers (low bitterness)? And I'm not talking cheap American beer water, because that is no good either to me.

I'm way late on this, but any sort of Belgian will generally be low in bitterness. Brown ales, stouts, and porters will be as well. It's hard to recommend anything in particular without knowing where you're located though. A lot of the Summer ales coming out will fit you fine as well.

Edit: Saw you're in Colorado, some off of the top of my head:

Avery Ellie's Brown Ale, Avery White Rascal, Left Hand Milk Stout, Goose Island Honker's Ale and Breckenridge Vanilla Porter are some standard recommendations but if you're looking to branch out to really interesting/world class stuff here's some recs.

Anchorage The Tide and It's Takes - A strong Belgian triple aged in Chardonnay barrels with a yeast strain known as Brett. This beer is complex with aromas and flavors of butterscotch, vanilla, banana, leather, lemon and oak. It's a bit pricey, but out of this world good.

Anderson Valley Gose - There's a blood orange and a regular. Both are tart like unsweetened lemonade, available in cans and low in alcohol. Some people find the tartness to be a turn off, some refreshing, so buy a single first if possible.

Ballast Point Grapefruit Sculpin - You say that you don't like bitterness and this is an IPA. This is one of the most fruit forward beers I've ever had though. If you like grapefruit then try a bottle.

Clown Shoes - Most of their beer in general is low in bitterness outside of their IPAs. Check into their line of stouts, they're all really good for what they are trying to accomplish.

Crooked Stave - This brewery makes a lot of funky and sour beers. If you're feeling adventurous these are some of the most rewarding beers around.

Dogfish Head Midas Touch - A beer, mead and wine hybrid, a really unique brew that makes for a nice desert pairing and is really approachable.

Goose Island Sofie - A saison (a Belgian style beer) aged partially in wine barrels with orange peel. This is a wonderful beer and I haven't met many people who haven't enjoyed this.

I agree, for the most part. I'm not all that happy trying everyone's IPA that tastes like everyone else's IPA at this point. They all taste more similar than different, and I grow tired of that pretty fast.

However, I simply cannot give up Ninkasi's IPAs, particularly Tricerahops, their double IPA. It's not gonna be everyone's favourite brew, but I feel that it is something a little special and unique, betraying the three letters printed on its bottle.
