[NSFW] How rated ‘G’ is the conversation around your office or classroom, etc.?

[NSFW!] Apparently if you mention anything pertaining to sex, or rape, etc. in a Fluther question you have to use a NSFW leader. But how rated ‘G’ is the talk around your workplace or campus? I have been in offices and on campus, where the talk of sex in all its colorful flavors was had without mincing words. Would a question be more work acceptable if it said penis as oppose to dick, swipe, pipe, etc.? If it said twat, pussy, honey cave, etc. it would be more offensive than if it said vagina? When sex is spoken around your workplace or campus is the phrasing very clinical and benign or more raw and explicit? If the talk is more explicit then why does it appear people get so uptight when it is printed or visual form?
