I was having a "discussion" with my little sister yesterday and she brought up the fact that I used to date one of her classmates a year or so back. I didn't particularly care, especially since they weren't close, but it gave me the idea to make a hypothetical poll post.

What makes a woman off-limits, if anything?

Personally? I avoid women who are or were involved with any of my friends. The first is obviously a moral point, I won't be the guy a buddy's girlfriend cheats with. The second part, though, is just to avoid drama. I would not mind if a friend hooked up with an ex of mine, but I know not all guys think that way and I would rather find another woman than risk a friend finding out and a huge argument possibly occurring. There are more than enough women in the world that I don't need that one.

So I added that and a few other classic examples, but by all means explain your choices, or why you disagree with one of the options, or throw in something I forgot
