most likely two situations for me: 1) things aren't going as well as they seem, and i end up in a bad position and have to deal with a lot of unnecessary and undesired issues. 2) shes in an open relationship (or else just likes to cheat) and i end up in a position i dont want to be in, and with a girl with whom a monogamous relationship isn't very likely to be possible. either way is pretty much not what i'm looking for, so i'd say no. oh a fling here or there would be ok....but only if they're single.
