I'm another who doesn't have that generic fear of rape. I don't think the weirdness it's about feeling unfeminine for me, so much as a fear that I have a kind of woman-not-afraid-of-rape privilege that means I'm interacting with women who do have that fear (more strongly) in a way that's bad or uncomfortable for them. (or possibly I'm interacting with men in a way that is unhelpful?) Because, yeah, having that fear, living that much of your life like that, must be hell and must have all kinds of unpleasant and unobvious to me consequences and side effects.
