I have no qualms about it at all. I don't see any difference between being stark naked or fully dressed — if it's part of the job and it's done with meaning and intention. I honestly don't understand the big fuss made over nudity and sex in films. It's silly. On TV, the children can watch people murdering each other, which is a very unnatural thing, but they can't watch two people in the very natural process of making love. Now, really, that doesn't make any sense, does it?
