Gonna second xkcd, Girl Genius, Go Get a Roomie, and Not A Villain.
Although it bears mentioning... the titular character in Roomie is not bi. She's homosexual. Fortunately, like the fun-loving little hippie she is, she's not bad about it. In fact, if I recall she even feels kinda bad for the guys that fall for her.
A couple of recommends of mine that have been finished (yes, that's right, as in 'done, not abandoned'):
Dominic Deegan: Oracle for Hire
Dominic Deegan is an freelancing oracle who's good at his job, but hates the usual riff-raff his trade attracts. And then one day he meets woman named Luna Trevoria and it all goes from there, eventually building up into one huge knock-down-drag-out climactic battle. Lots of sarcastic wit, terrible puns, and crowning moments of awesome. Fair warning, though: the author, Mookie, is a big-time death metal fan, and Dominic Deegan reflects this. Bad things happen, people screw up, good people get maimed and/or killed. But over all, it doesn't fall anywhere close to grim-derp territory.
Darwin Carmichael is Going to Hell
Pretty much what it says on the tin. In a world where the natural and super-natural walk openly side-by-side (seriously, he got a bunch of angelic roomies that are complete pot-heads, a pet manticore that thinks its five years old, and his other roomie is an artist with his very own muse), Darwin Carmichael has a huge nasty black mark on his karma and is going to go to hell if he can't fix it. Story meanders quite a bit, but it is chock full of great character development. Might also be NSFW - can't recall for sure.
