I'd prefer minimal relationship angst (hence, not necessarily a romance.) Ideally when they get together they stay together and live happily ever after.
No cheating. NO BDSM elements - zip, zilch, nada. Explicit sex is OK but not required.
Not too concerned about the genders of the partners but I'll say that I have a thing for strong female characters. This doesn't preclude a strong partner but I'm not looking for the alpha male, big he-man stuff (which usually devolves into some sort of dominance BS anyway.)
The relationship doesn't need to be driving force of the story (low angst there means there will most likely need to be another source of conflicts) but it should be a major part of it.
Fantasy, SF, Western, contemporary, etc... - they're all fine. Humor is always a good adjunct.
For examples I've recently enjoyed Oyster50's stories, Heathen57's "A Friend in Need", WTSMan's stories, Renpet's. It would be kind of nice to keep them in the same generation for a change for a while but I'm open to intergenerational as well.
Anyone have anything that they particularly love that fits the bill?
