Clearly some women are conniving underhanded b1tches who don't actually trust the men that they're with.
Like I said, if my gf tried that with me she would be shown the door and kicked out.
I actually pity them - they have been socialized to think that this is how women ought to behave. The magazines tell them to do so, their own mothers tell them to do so. They try things like that in the real world, and a lot of the time, it ends badly for them. And they wonder why.
