Is there an option to turn off nudity or strong language?

The only (and very brief) nudity appears if/when you decide to consummate a romantic liaison.  Which it is totally within your control to decline, and which scene you can skip with a quick press of the [Esc] key.

"Strong" language, on the other hand, is a little less avoidable.  Several of your companions have a coarser vocabulary than you might like.  Although I must say it fits their personalities very well.
