I'm still struggling with the subtleties of the English language, so I have a question for the native english speakers on my flist. I was reading slash lately (big surprise) and I was wondering about some words, the terms "slut" and "whore" in particular. In German (like in French or Italian) most nouns have a gender. The translations of both this terms would be female in German, so they sound a bit awkward to me, when I'm reading them in slashfiction.
So I'm wondering, do they have a gender implication in English too, or would you say you perceive them as gender neutral? I dimly remember Brian being called a man-whore once, so I suspect that at least whore has a female implication,somehow.
