Guys, what do you think?

Would any of you guys out there actually avoid forming any kind of relationship with a girl, just because she smokes? A lot of guys seem to think that it is 'unladylike'. Unladylike? How about sexist? Anyway, I'm digressing here. What I really am curious to know is whether smoking is actually a significant factor in enticing/deterring potential guys. All I know so far is that it sure doesn't seem to be that big a deal when guys do it.
