I agree with those saying nudity can be artistically important, and I think it shouldn’t be censored. I will also say that I have trouble watching movies with explicit nudity with family members, and the same goes for sex scenes (that may or may not contain nudity in frame). That sort of stuff just makes me immensely uncomfortable around others. It might be a subconscious desire for personal approval, but I really can’t tell.
Even just with your siblings?
