Except those would have been entirely legal, consenting adults and all that. In the 90's only erect penises, penetration shots, children or animals would have got you put away. These days not even the erections or penetration. This was a significant over-reaction by the pointy heads. Inventing their own laws.
As a rule I always let the company know if I'm taking nudes to be developed or printed. It gives them an opportunity to pass on this job, or keep it away from any school leavers. (Yes, I'd have loved to see them when I was 16 but the law disagrees.) My local independent doesn't turn a hair though, seen it all over the decades. I take it as a badge of honour on the rare occasions that I manage to surprise her.
