Consider this: if I bump you (even unintentionally), by the strictest reading of the law, I committed assault and battery. That's obviously ridiculous, so we use our common sense to keep society functioning. We consider intent, and the likelihood that someone would feel genuinely threatened by someone else's actions. SO, to paraphrase your example: an average woman, who might lack the physical means to feel safe in the presence of someone who might be larger and looking at them in a sexual way, would be justified in feeling threatened.
