Nudity seems to be an issue that America can't get over in general. I wonder when the day will come when we finally become okay with it, with the human form.
I've never done any nudity, but I would do basically anything if a role called for it.
Always ask for what you want, because the worst thing that can happen is embarrassment but the best thing that can happen is nudity.
I'm not opposed to nude scenes, if they're appropriate. I'm not against them morally. But I personally no longer find movie nudity to be worth my while.
