It’s a wonderful little item on the World Service about the man who drew the illustrations for Alex Comfort’s unbelievably illuminating Joy of Sex.
The book was a breakthrough for many young couples in the particularly bleak British 1970s and I can call to mind the drawings without having to shut my eyes.
But hearing how they were done has slightly dented the fantasy. I’d rather go back to my innocent preconception.
This is, by the way, currently the most watched item on the BBC News site.
