I'm a total prude about this and it's seemingly unavoidable. Most recent was introducing my mum to Breaking Bad and forgetting about the post-clothes shop dust-up bang between Walt and Skyler.

Once we watched One Foot In The Grave together and I thought we were safe, but somehow the episode contained a scene with Angus Deayton and his wife having a sexy weekend away, and for some reason the hotel had a two-way mirror so people could watch. So fucking creepy and weird.
